They also charged different prices for the same item depending on where in the store you found the item. I went in once to buy the Original Capt Scarlet Series DVD boxset which I'd heard they had on offer for 14.99. I made a B-line for the TV section and there was one boxset priced at £70. I took it to the checkout, thinking it would come up at 14.99 but it checked out at £70. I told the assistant I'd heard they were selling them for 14.99, he checked it through again and said nope it's £70. I said I didn't want it and offered to put it back. As I went to put it back I noticed at the end of the aisle, a pile of the same boxset marked up at 14.99.
I've seen that happen as well. Did you get it at £14.99?
