:00:00. > :00:08.Tonight on Inside Out, we go undercover at Britain's
:00:09. > :00:11.biggest supermarket, Tesco.
:00:12. > :00:26.And we go in search of gold in one of the unlikeliest of places.
:00:27. > :00:29.Welcome to Inside Out, I'm Paul Hudson.
:00:30. > :00:33.Tonight, we are investigating Tesco, Britain's biggest supermarket,
:00:34. > :00:49.where some special offers aren't always that special after all.
:00:50. > :00:50.Also tonight, the artist hiding real treasure
:00:51. > :01:02.And later in the programme, top archaeological finds
:01:03. > :01:08.You can see he's got quite a wide rood here,
:01:09. > :01:13.and that's probably something like an axe.
:01:14. > :01:17.Now, how often do you check your receipt when you shop at Tesco?
:01:18. > :01:20.We all take for granted the price we see on the shelf
:01:21. > :01:23.is what we pay at the till, but what if it's not?
:01:24. > :01:25.Well, Jonathan Gibson has been investigating
:01:26. > :01:32.the not-so-special offers at Britain's biggest supermarket.
:01:33. > :01:45.That's why the shelves at Britain's biggest supermarket
:01:46. > :01:49.are full of special offers - money off this, buy two for that,
:01:50. > :01:53.you get the drift, and we all take it for granted that the price we see
:01:54. > :01:57.on the shelf is the price we'll pay at the till - right?!
:01:58. > :02:00.But what if things don't quite add up when you get home
:02:01. > :02:06.I've just bought a few bits at Tesco and I'm sure these products
:02:07. > :02:11.were on special offer - that's why I've bought two of each -
:02:12. > :02:16.but according to my receipt I've paid full price!
:02:17. > :02:22.I've paid 60% more than the deal on the shelf.
:02:23. > :02:30.At another Tesco store, I spot 2 for ?2.00 on ice cream.
:02:31. > :02:36.But at the till, it's the full price as well, so what's going on?
:02:37. > :02:41.Martin works for Trading Standards and says the law
:02:42. > :02:49.They must put a price on goods so you know what you're going to pay
:02:50. > :02:51.and that price must be accurate so you don't get charged
:02:52. > :02:56.more than you thought you were going to pay.
:02:57. > :03:01.Sounds simple enough and with more than 3,500 stores nationwide,
:03:02. > :03:10.That's what I want to find out so armed with my phone and some
:03:11. > :03:13.secret cameras I want to see how many offers on the shelves don't go
:03:14. > :03:26.through at the checkout, and here in Leeds I'm finding problems.
:03:27. > :03:29.After checking the price on the shelf he asks his colleague
:03:30. > :03:39.But neither of the staff remove the out-of-date label so,
:03:40. > :03:41.when my colleague returns a few hours later, we're
:03:42. > :03:46.Multi-buy deals are being left on the shelves after the tills have
:03:47. > :03:51.This offer is almost a month out of date and it's not
:03:52. > :04:03.At this Tesco superstore on the outskirts of Leeds,
:04:04. > :04:05.a worker checks the label but he doesn't spot
:04:06. > :04:16.It should have been removed five days ago.
:04:17. > :04:21.I've started making a list of how many offers are wrong in how many
:04:22. > :04:25.places and I want to know if what's happening in Yorkshire is also
:04:26. > :04:34.Because, if it is, it's not just a problem for Tesco,
:04:35. > :04:47.At this Tesco store in Liverpool, sauce marked ?1 on the shelf
:04:48. > :05:01.And at another store nearby, I'm left completely confused
:05:02. > :05:03.by the offers on the shelves and what I'm charged
:05:04. > :05:08.In fact, there's so much difference between the shelf price
:05:09. > :05:10.and the receipt price, I'm not even going to bother
:05:11. > :05:16.to go back and try to get what I'm owed returned.
:05:17. > :05:27.If there are just too many offers changing too frequently so that
:05:28. > :05:32.store staff can't really be expected to understand them, comply
:05:33. > :05:36.with all the changes, then that is something that Tesco
:05:37. > :06:02.And there's plenty to think about when I head back to Leeds.
:06:03. > :06:04.Doing now what somebody should have done hours, days, weeks ago.
:06:05. > :06:25.That's a serious message but is everyone taking it seriously?
:06:26. > :06:28.And as I head around the country, the same thing keeps happening,
:06:29. > :07:16.It doesn't seem a terribly difficult or perhaps that long a job,
:07:17. > :07:18.just to walk round the store, assuming everyone knows
:07:19. > :07:22.what day it is, you know, to go round and tear off anything
:07:23. > :07:38.And it's not just shoppers left confused as old and new promotions
:07:39. > :07:53.The longer the offer has been wrong, the bigger the failure of diligence
:07:54. > :07:56.and the more worried I am, frankly.
:07:57. > :08:01.In that case, he's not going to like what's coming up next.
:08:02. > :08:03.At this store, the cashier checks the out-of-date label
:08:04. > :08:08.And when I return the next day, neither does someone else.
:08:09. > :08:12.So, a week later, I go back, and it's still on display.
:08:13. > :08:16.And when I return a month later, yes, still on the shelf.
:08:17. > :08:19.The fourth worker finally removes it.
:08:20. > :08:25.It's pretty basic that if one customer is shown something wrong
:08:26. > :08:32.then it's put right to stop other customers being misled.
:08:33. > :08:36.But at 33 of the 50 stores I went to, the till price was more
:08:37. > :08:46.If customer A has come back and complained and been refunded,
:08:47. > :08:49.that doesn't mean there weren't 20 other customers who didn't spot it
:08:50. > :08:59.There were obviously major problems with their control of the special
:09:00. > :09:03.offers and it's the special offers that bring people in,
:09:04. > :09:06.make people reach for more and perhaps spend a little bit more
:09:07. > :09:08.than they're meant to when they came into the store,
:09:09. > :09:16.The company wouldn't provide anyone for interview
:09:17. > :09:36.but after reviewing our evidence told this programme...
:09:37. > :09:42.Following our investigation, Britain's biggest supermarket says
:09:43. > :09:46.it's now doublechecking the accuracy of every price in every store -
:09:47. > :09:51.that's more than 3,500 stores across Britain.
:09:52. > :10:03.And don't forget, if you've got any comments about the night's programme
:10:04. > :10:06.or you've got a story you think we might like to cover,
:10:07. > :10:09.you can get in touch on Facebook or on Twitter.
:10:10. > :10:11.Coming up on Inside Out, the archaeological treasures hidden
:10:12. > :10:23.Now, there's a chance to find some modern-day treasure
:10:24. > :10:28.An art exhibition is opening in the town.
:10:29. > :10:32.The paintings will contain clues to a very special treasure hunt.
:10:33. > :10:38.Anyone can take part and the prize is real gold, I kid you not!
:10:39. > :10:48.It's winter in Scunthorpe - not the most promising place to be
:10:49. > :10:52.But later this week, people here will have
:10:53. > :10:59.a golden opportunity - quite literally.
:11:00. > :11:02.We've got five golden artefacts that have been created.
:11:03. > :11:05.They are going to be hidden in and around Scunthorpe.
:11:06. > :11:10.But to find them, you'll need to crack a code.
:11:11. > :11:13.One of them is supposed to be ridiculously easy.
:11:14. > :11:16.Each gold object is worth ?1,000 and if you find it you keep
:11:17. > :11:24.It's all in the name of art and Luke Jerram is the artist behind
:11:25. > :11:32.I had this idea to think about celebrating the history
:11:33. > :11:38.of Scunthorpe by taking five objects from the museum and created
:11:39. > :11:42.So tell me about the statues themselves.
:11:43. > :11:47.They range from a Jurassic ammonite, which will be millions of years old,
:11:48. > :11:51.all the way through to a genus train, which is taken
:11:52. > :12:02.We've also got a Roman ram and this beautiful Tudor figurine as well.
:12:03. > :12:07.But finding these ?1,000 solid gold objects will not be that easy.
:12:08. > :12:10.Treasure hunters will have to crack a code which is hidden in paintings
:12:11. > :12:14.to be displayed at the 2021 Gallery in Scunthorpe.
:12:15. > :12:17.And the paintings are being created at this not-so-secret
:12:18. > :12:24.Each artefact has a painting that goes with it, and the painting
:12:25. > :12:28.contains clues as to where to find this gold artefact.
:12:29. > :12:32.There are five paintings and five objects.
:12:33. > :12:36.Luke has asked artist Vivienne Baker to make the five paintings.
:12:37. > :12:39.Today he's come to take a look at how things are progressing.
:12:40. > :12:44.Not that surprisingly, all the clues will be in gold.
:12:45. > :12:50.Yeah, it looks nice, though, doesn't it?
:12:51. > :12:54.The paintings are like backgrounds, like something solid
:12:55. > :13:20.There's no way I could crack the most difficult one.
:13:21. > :13:24.I could certainly crack probably two or three of the paintings.
:13:25. > :13:26.You say that now you know the answers!
:13:27. > :13:32.I've been working with a guy from an unnamed government agency
:13:33. > :13:40.to work out all the coding and the ciphers for these paintings.
:13:41. > :13:44.Some are really easy to decode whereas the most
:13:45. > :13:48.complicated painting, it will take maybe a month
:13:49. > :13:54.I know you're not giving a lot away, you don't want us to suss
:13:55. > :13:58.out the clues just yet, but can we speak to the man?
:13:59. > :14:13.So I've managed to persuade Luke to give me the details for his code
:14:14. > :14:16.man and now I'm heading back up North to meet him.
:14:17. > :14:19.I'm at Sheffield University to meet mathematician and secret code
:14:20. > :14:24.How on earth does a mathematician get involved with an art
:14:25. > :14:28.Well, it was quite a surprise, really.
:14:29. > :14:31.One day, there was an e-mail going round.
:14:32. > :14:35.The header was just puzzler/codebreaker required.
:14:36. > :14:39.I just tried to resist the temptation to open it but I failed.
:14:40. > :14:42.How many people know the answers to the codes?
:14:43. > :14:47.How difficult are the cyphers that you've set within them?
:14:48. > :14:53.So there are five in total and one of them is supposed
:14:54. > :14:59.The final two in particular are much harder, so we're expecting at least
:15:00. > :15:02.one of them to go unsolved for quite a while.
:15:03. > :15:05.To give me a fighting chance, Dan shows me how to solve
:15:06. > :15:10.So what I've used here is something called a Caesar shift.
:15:11. > :15:14.It's a very old cipher and basically all I've done is I've took
:15:15. > :15:17.the alphabet and I've shifted it on one place.
:15:18. > :15:39.This one follows a bit of an extended rule from that one,
:15:40. > :15:42.so can you try and figure that one out for me?
:15:43. > :15:46.that's a jump forward, that stays the same,
:15:47. > :15:48.that's a jump forward, that stays the same.
:15:49. > :16:01.Well, I don't think they'll be recruiting me for MI5 any time soon.
:16:02. > :16:07.We took the file, we printed it and now we need to put a feeder
:16:08. > :16:12.Meanwhile, at a secret location elsewhere in the country,
:16:13. > :16:15.some very talented people are working to finish the gold
:16:16. > :16:20.objects ready for them to be hidden in five locations around Scunthorpe.
:16:21. > :16:23.Originally, it's a Viking brooch that was found
:16:24. > :16:33.It reminds me of all the wind turbines in Scunthorpe.
:16:34. > :16:37.We are putting the wax into the mould.
:16:38. > :16:41.We are going to melt the wax out of the mould.
:16:42. > :16:48.And then, through that tube, we will feed the metal to make the piece.
:16:49. > :16:53.Right, ready to go, and we will roll it over.
:16:54. > :16:56.There is this lovely moment of alchemy when you're holding
:16:57. > :16:59.precious metal and you're melting it down and it's being transformed
:17:00. > :17:02.into another form, there's something quite magical about that.
:17:03. > :17:16.We've gone from a 3D object to scanning to wax into plaster
:17:17. > :17:27.Look at that, solid gold worth ?1,000, I wonder
:17:28. > :17:40.So I'm off to meet the man whose job it is to organise the exhibition.
:17:41. > :17:57.We are in Scunthorpe Centre. We close to where any figures are
:17:58. > :18:03.hidden? There are some in urban locations, some in parkland and some
:18:04. > :18:08.a bit further out of town. You worried that people will dig up all
:18:09. > :18:18.the parks? It was a concern so we were very careful not to bury any of
:18:19. > :18:21.the objects. It will be difficult to hide them. Should we go in
:18:22. > :18:26.balaclavas in the middle of the night? We're not sure. He might have
:18:27. > :18:35.to shake your bid. So, if someone finds the object
:18:36. > :18:38.they get to keep it, and they will then decide
:18:39. > :18:40.whether to melt it down Or they can keep the artefact
:18:41. > :18:44.for artistic reasons, so that's interesting as well for me
:18:45. > :18:47.what the value of an object is, is it just the value of the gold
:18:48. > :18:51.or does it have more value as an artefact, as an artwork
:18:52. > :18:54.in its own right? hiding the objects under the cover
:18:55. > :18:59.of darkness, but you've guessed it, The exhibition starts
:19:00. > :19:07.here in Scunthorpe at the weekend Now, most people know
:19:08. > :19:20.the Yorkshire Wolds for its rolling hills and stunning views,
:19:21. > :19:25.but it has got another claim to fame - as one of Britain's richest
:19:26. > :19:29.archaeological sites. We sent intrepid explorer
:19:30. > :19:38.Paul Rose to investigate. With thousands of acres
:19:39. > :19:44.of lush farm land - you could be forgiven for thinking
:19:45. > :19:47.that all you'll find in the Wolds But just a few feet below
:19:48. > :19:52.the surface of this chalk rich landscape there are epic stories
:19:53. > :19:55.of the black death, extreme violence They're all there if
:19:56. > :20:00.you dig deep enough. I'm going to take a journey back
:20:01. > :20:04.in time through the wolds - a place that has provided some
:20:05. > :20:19.of the country's most significant It's very productive landscape in
:20:20. > :20:25.prehistoric times as is the day, and all that activity has left its mark.
:20:26. > :20:28.You can go back through time periods, whether it is prehistoric
:20:29. > :20:34.Mesolithic material through the Bronze Age, the Iron Age, the
:20:35. > :20:36.medieval period, the Romans, and see how humans have shaped informed that
:20:37. > :20:43.landscape. The most famous of the wolds'
:20:44. > :20:45.archaeological sites is the deserted medieval village
:20:46. > :20:49.of Wharram Percy near Malton. And here there's still
:20:50. > :21:01.lots to actually see. For 700 years, there was an active
:21:02. > :21:05.community here, and this is what remains of the church and hub of the
:21:06. > :21:10.whole village. A combination of the Black Death and the way the lad was
:21:11. > :21:12.farmed meant that by the early 16th century the village was effectively
:21:13. > :21:14.abandoned. Archaeologists have had a field day
:21:15. > :21:16.trying to understand In the 1950s researchers moved in,
:21:17. > :21:35.and they stayed for 40 years You are not just looking at the
:21:36. > :21:39.building or a castle. You are looking at the every day, how these
:21:40. > :21:49.people ate, had they produced food, how they lived. That makes the
:21:50. > :21:52.excavations stand out because it gives all that contact the daily
:21:53. > :21:57.lives of ordinary people. People like us.
:21:58. > :22:02.The Wharram Percy dig is now over but, nearby on the wolds,
:22:03. > :22:03.archaeologists are still hard at work.
:22:04. > :22:09.from Manchester University are working on an extraordinary cold
:22:10. > :22:17.case that's taken me even further back in time to the iron age
:22:18. > :22:25.I am on the Trail of the burial that was found when it was snowing in
:22:26. > :22:35.1980. Originally discovered by members of the Army. The excavated
:22:36. > :22:38.what they thought was a shell and it turned out to be an iron sword.
:22:39. > :22:44.It was an amazing find of the lost burial site
:22:45. > :22:46.of what appeared to be a significant figure.
:22:47. > :22:50.The grave occupied a prime position with grand views all round.
:22:51. > :22:53.And the fact the sword was bent but not broken was probably a sign
:22:54. > :23:00.that the weapon was ALSO laid to rest along with its owner.
:23:01. > :23:10.It's a dramatic burial with the sword Ben. We can imagine the wood
:23:11. > :23:20.of the scabbard shattering around the blade. So this man somehow had a
:23:21. > :23:22.place high in society? I think so. I want to understand his life as well
:23:23. > :23:26.as his death. Mel's team are looking for more
:23:27. > :23:29.clues near the burial site but what's clear is that this
:23:30. > :23:31.warrior met a violent end. First, I am going to show you his
:23:32. > :23:39.skull, it is very fragile. His remains have made the short
:23:40. > :23:50.journey to Hull Museum. That fine line has healed, so that
:23:51. > :23:54.the sharp thin blade. It goes hand-in-hand with an injury at the
:23:55. > :23:59.back of his head, which is a much larger wound. He has got a wide
:24:00. > :24:08.wound here and that is something like an axe. Its gates across the
:24:09. > :24:12.scalp, he gets away with it. Unfortunately, the next time he
:24:13. > :24:17.meets the sharp end of the sword, he does not survive. We have got three
:24:18. > :24:18.injuries at the back of the head, or one there, and another one at the
:24:19. > :24:26.top of the head, quite deep pond. He may have died by the sword
:24:27. > :24:38.but new data has shown that this man Can you see that discolouration on
:24:39. > :24:45.the rip? There, particularly, can you see how bumpy it is? It looks
:24:46. > :24:48.almost like dirt. It should not be there. It is as body reacting to
:24:49. > :24:51.severe infection. The warrior had tuberculosis -
:24:52. > :24:53.a debilitating chest infection that Scientists believe it's the second
:24:54. > :25:09.earliest case of TB to have Whether there's a conflict and he is
:25:10. > :25:12.so poorly he is unable to defend himself, whether members of his own
:25:13. > :25:16.community despatching because they do not want this disease to spread,
:25:17. > :25:21.they are worried, they may even see him as being cursed by the gods,
:25:22. > :25:29.another possibility is he may want to grab death the throat, go out in
:25:30. > :25:30.the glorious end, and it is snowing that his comrades will promise him
:25:31. > :25:37.the sender. That's quite something. While some stories take
:25:38. > :25:39.ages to piece together, others are uncovered
:25:40. > :25:43.by mother nature. Close to one of the world's great
:25:44. > :25:51.superstructures is the site of one of the Wold's most
:25:52. > :25:53.remarkable discoveries. Ted and Willy Wright -
:25:54. > :25:58.found planks sticking out of the mud The wood looked like it
:25:59. > :26:06.was once part of a boat but how old it was -
:26:07. > :26:16.well, that came as a complete The shape of the boat at the
:26:17. > :26:20.brothers to believe it was a Viking craft but the reality was much more
:26:21. > :26:29.exciting. This boat was over 4000 years old. These planks were
:26:30. > :26:37.situated in a gloopy, horrible mud. How they manage to do it. What a
:26:38. > :26:43.complete and utter nightmare. The gloopy mud acted
:26:44. > :26:45.like a preservative playing a key part of the survival
:26:46. > :26:48.of what remained. Over the course of several decades,
:26:49. > :26:51.three boats were discovered - and their design has led historians
:26:52. > :27:05.to believe they were capable They were plank built boats made out
:27:06. > :27:08.of seven or eight planks. All three boats show a base plank with planks
:27:09. > :27:14.attached to the side of it and they are literally tied together. We have
:27:15. > :27:18.got evidence were they are driving in Moss to make the boats
