I have a grudge against Argos because years ago I had to queue for ages (it was near Christmas) to pay for something and then queue some more to pick up the thing I had paid for, and then found they had run out so had to queue again to get my money back.
I also won't shop in Electrons Boutique (or Game as they are now known) as they pre-sold me Formula 1 '97 for the PS1 for about £50 by telling me I would get a nice F1 book with it. When I wnet to buy the game they said the books hadn't arrived yet and I was to come back the next week which I did and was then told they had run out.
Don't get me started on Dixons and my Mega Drive buying experience! We are much better off with GBAX.com, Play Asia and Lik Sang.
