How much would my Xbox, Xbox 360, Playstation, my 3DS, my GameBoy Advanced SP, and a bunch of wires, controllers, games, etc sell for? I would like at lowest 100$ USD for it all. Thanks...

There's no way for us to tell you. They'll want to see the condition everything is in, and the games probably matter more than the consoles honestly. Some games could get you a really good price. Others they might might even take. It's hard to say

$43. 76

You would have to either call. Or go there and ask. I know they'll pay decent money if everything is in good condition.
