They're both gross, but I'd rather know my games I'm buying haven't been left in some place to collect dust.
How old are you Glorb, and why are you paying all that stuff by yourself? I pay for that stuff to, but I still prefer to buy factory fresh games, unless they're old, impossible to find or sold at ridiculously high prices (eBay sellers love to do this). Though I usually wait for deals and mailed coupons to use when I'm buying stuff.
