How much is a used 3DS plus these used games worth (Mario Kart 7, Pokemon Y and Pokemon Rumble Blast)

Dude if that 3DS is in good condition, all that for $100 is a good deal

Pokemon Y and MK7 alone still go for near full price. Rumble Blast is crappy but consider it a bonus. Ask him how long he's had the 3DS for and if it functions fine then grab it.
