I think this is worth a new post, especially considering the price.
I was having a speculative look around Sainsbury's about an hour ago. When I noticed a young lady with a trolley full of goods, I got her to do a price check on a TomTom Europe that was in there, she said it was £19 but it's reserved, but she found one other out the back. Couldn't believe it, I thought the £45 deal on the V4 UK I got yesterday was astonishing.
I hope this isn't a one off, happy hunting!.
