yes you can, but the prices will be diffrent and you will only know how much (unless you convert the price yourslf) it costs at the till.

Duty free is a waste of time, if your coming to england, save your money, you will get much better deals on the high streets.

Duty free is a scam because they charge at RRP. if you buy a PS3 game, it's £49.99 -17.5%, which is nothing.

on the high street, you could pick up the same game for £29.99 or less. and it's the same for electronics and pretty much anything in duty free except for ciggrettes or tobacco.

I think (not 100% sure) that there is a forign exchange were you can change your money should you find they dont accept it for some reason.
