Hey, sorry if this has been asked before, but I couldn't find an answer. Anyway, I want to know if I could buy two PSX games and get one free PS2, GBA or GC game; or do all three games have to be for the same system? Also, could I get two crappy, cheap games and get a third game that is around $20-40 used for free or do they have to be around the same price as well?
