Is there a good website for checking supermarket prices?

[TracyK]

I've a list of food items that I only buy when they are on special offer.

I've been picking stuff up as I go round each supermarket - varies each week where I go. Is there a more proactive way to seek out bargains?

mysupermarket.co.uk compares the prices of sains, tesco, asda & ocado
