Where could I find a cheap 3ds?
You can find cheap 3DS games at www.cheapassgamer.com or at www.cheap3dsgames.com. The prices range from $19.99 to $29.99. Examples of the 3DS games they have include Ace Combat, Animal Crossing, Batman, Battleship, Dream Tiger and Fantasy Life.
You could go to any game store and they sell used 3ds's for cheap but not new ones
For me this website is the best http://tinyurl.com/bss758x . Especially love their shipping policy…
