Do You sell 3ds or 2ds?

Yes they do ask for one if you get there

I called my girlfriend that works for gamestop, and even got prices. 2ds' run from 75-80 and 3ds are 150-160. Of course you can drop that price by buying preowned, and getting a pro card or elite procard. You spend a few bucks on the card, but get savings on preowned and more cash back when you trade in games and such. Pays for itself if you plan on getting more games for your new system.
