What is the most you can get for your Game Boy Advance SP?
In Person/Ebay: 80-120$
this is my guess but it is pretty educated because you can only get 40$ for a DSlite
you can only get about 20$ for a Nintendo Gamecube at gamestop
take this word of wisdom NEVER NEVER NEVER NEVER sell your stuff to the pawnshop they will give you NOTHING NOTHING they give you almost nothing and sell it about 2 times more expensive for what you got for it NEVER sell your stuff to the pawnshop
