Ok so I want a 3DS and I got a new DSI, a PSP, and I want to trade about 5-9 games, (for both PSP and DSI). I just want to know how much it would cost after I trade in all that.
It really depends whether the games or new or old and whether they are games with good ratings. If they are then you should have to pay much at all. assuming you have all the original boxes and warranty's as well as manuals and what not. If there are no scratches there shouldn't be too much deducted. You will have to pay a bit 20 0r 30 bucks max. Also choose the store carefully visit a collection of stores and pick the one that offers you the best deal. Don't jump on a deal because it sounds okay go to other places as well.
