I upgraded my DS and now I want to unload my old DS phat and my old cart and SD card. What is the best site for selling something like that? one that isn't going to take a big chunk of my sale. also, what do you guys think its worth as a package? It's a: DS phat, platinum M3 SD ( original size ) 1GB SD card and of course, all boxes and stuff like that. help me, 'cause I need to recoup the monies!
