Almost all PSP games are $.99 at Best Buy and bestbuy.com. Preowned only.
Everything good is probably in store only at this point though. You know how sales like this are when the word gets out. By the time the word gets out, it's usually too late.
*edit*
Everything is in store only. When a deal like this comes along you know you're too late for anything. If any of you have a Best Buy close to you, may as well check out the store and see what they have in stock. I think Rock Band Unplugged is the only game not $.99.
