Ive had pretty good experiences at both my retro gamestop. I got a gamecube all oem cords and controller $60, n64 with oem cables and controller $50, def jam gamecube $80, halo 2 $3 and mario party 2 for $25. It was mostly xbox or ps3 games with oldest being n64 games. Only thing I would say was eh was pokemon diamond and pearl being marked up by like $20.
