Forgive me, I don't know where to put this... HMV are, from today, taking pre-owned games and giving you either cashback, or a gift voucher/trade-in for anything in the store. After taking Mario Charged football for the wii into my town centre to check with game,gamestation and cex, I was plesantly suprised that HMV offered me 3x what game and gamestation were offering.
According to the cashier, this only started today, but is going to be a permanant thing
With everyone strapped for cash at the moment, getting rid of a few games, even to get some Christmas money, I thought this might be useful to know
PS: They offer more for games in "mint" condition, so polish up the discs before you go ;)
