$20
It depends on what controller your trading in
$19.99 for game of year
If you're talking about you trading it in for money, I can imagine they won't give any more than $20-$30.
Gamestop no longer takes GameBoy Advances.
if you are asking how much money it is i got it at gamestop used for the ps3 for only 14.99 and it works great
Depends on what titles you are selling/trading.
It depend if it is gamestop they will give 30 % of regular price
instead of trading at gamestop which won't get you much. sell it at eBay abd let the bidders do the rest. after that use the money to buy a ds lite or NEW DSI. or you could give it to me
$1.50
$1.
75.00
The amount of money that GameStop will give you depends on 2 things, what type of condition of the DSI is in, and the store that you are in
