You should check out trading them in during a promotional period at gamestop because sometimes they have pretty good ones you might be able to trade them all in and get a gift card to buy a ps4
OP: I have all this stuff I want to trade for a PS4.
Gamestop: I'll give you 50$ and fuck off.
Lol GameStop probably will tell me heres $50 now F off. But, its worth asking. Cant hurt anything.
