Closing down - everything must go!!

"Was £750 - now only £350" - does anybody really take any notice of such adverts? Does anybody really think "Ooh, what a bargain - I can't pass that up!".  I find it difficult to believe, but the fact that the Office of Fair Trading is demanding that six (unnamed) high street stores justify these sort of statements, or stop using them, suggests that there are those who are taken in by them.  Surely the only question is - am I prepared to pay £350 for it (whatever it is).  What it may or may not have been on sale for previously is of no consequence.  This is the here and now.
