yungmagic09, for me it takes 2 days to get a game. They process them very fast. New releases aren't guaranteed but I would say almost 9 out of 10 times I get it sent out on launch as long as I kept it in my queue for a little bit before the release date.
Funny thing is if you get the game on day one you pretty much get a new copy, but you can buy it from Gamefly used for about 42 dollars, so it can be cheaper than retail. Old games can be purchased, like I got Wolverine for 2 dollars and some reward coupons I built up just by being a member.
