Linked Anny to this a few days ago and meant to post it here too but i forgot.
When i've ordered games in the past i've usually just gone straight to somewhere like GAME/Play.com without looking elsewhere, but i recently started using GamesTracker to search for game prices and found myself some (that i'd consider) real bargains which i wouldn't have seen otherwise - Mass Effect for 14.99 which i posted about a while ago, also Lost Odyssey 12.99 & Blue Dragon 8.99 both inc postage.

Hope some of you find it as useful & money saving as i have.
