Amazon has crazy deals online you should definately check this site often. They have deals like discounts on day one purchases, $15 - $20 discount on future purchases, and you can have it shipped so they arrive on release day (READ: you would get it on the day it came out just like you would have took your ass to the store to get it)

Then there is the lightning deal of the day, a random game gets a major discount. And its not just crappy games its good ones too I saw Killzone for $20 one time and just a few hours ago the Tekken 6 Bundle that regular price is $100something go for $30.

So yea with all the savings and deals you could really rack up on games and save way more money.
