remember that amazon did have this onsale day 1, it was 57.99 with a $10 promo credit
I'd think that aggressive $41.99 price point is a direct result of gamestop offering the game used for $42.99
also, speaking as a cag, that's what this site is all about, games going on sale, games getting price drops, games getting cheaper. Day 1, Day 10, Day 100 prices trend downwards, it's great for consumers.
