On an impluse, I bought a Nintendo DS the other days, along with a Momma's Cookin game from a EB Games store. I've played it a bit and regret my decision and want my $160 back !! Will I be able to return an opened box, or will they buy it back for less money? Should I try a different game and see if I like that better? Does anyone want to buy a Nintendo DS at a discount?!
