believe me, im not a fan of our policies, none of us are. if it were my business id be super strict. no case and no manual? no thanks. who wants to pay full price for a game with no instructions or no cover art? not me. what, do people throw them out?
id bring back a system much like toys r us used to have where they had display art and you brought a ticket up to the register, no more of this opened copy crap.
personally i think the amount of trade in credit given should be dependant on the condition of the game. and if possible, we should charge prices that are determined by the condition of the game, just like EVERY other hobby. you want a near mint used game? ok that'll cost you $55, the kinda beat copy is $25.
i can't speak for any other store but my coworkers and i do our damndest to give customers the nicest copies on hand and were very strict on what we take in, stricter than company guidelines actually. if i wouldn't buy it, i wouldn't sell it to you.
