how much do you think i could get for...

Dude, thats worth like over $250. Depends on what games and movies you have for the PSP. But still it has to be over $250.

Places like Game Stop have all that information in their computers. They don't decide have much to give you. It's all pre-set in their system. Depending on the game and it's popularity and how old it is, they will give you more or less. Some games they may only offer $1 for. Newer titles will be more or course. You have to basically check it out and see, you may be better off selling the stuff privately depending on what it is. In a Pawn Shop you may be able to haggle with the guy more than a Game Stop. Still, its best to look around and don't give the stuff away for next to nothing just because you're in a hurry. Maybe try to place an AD somewhere. Try craigslist.com....look on the right side and find the area closest to you. There you can place ADs for FREE. Good Luck

If you have a game stop near you, call them up and ask what their prices are for trading these items in. They'll be able to help you.

Sell it on Ebay, not at a pawn shop.

try gazelle.com

the site came out like three days ago, its like ebay, but you could be 7 and sell something.
