If I buy a used game, don't break the sticker, then return it 6 days later, is that 'abusing' it?
I used to spend more to buy from EB because of their generous return policy. I returned maybe three games, and two of them I returned the next day. One game, yes, I almost beat within 4 days and returned it for that reason; my thinking in that case was 'If I almost beat it in 4 days, is it worth 30 bucks?' answer of course was No. But I played the crap out of, and kept, the game I exchanged for it.
Now, people who sliiiide the sticker off, or somehow re-seal it after playing and beating it then return the game, that definitely is abuse.
I assume if, once you open it, if you find the disk is scratched all to hell, they'll still take it as a 'defective' return? [maybe exchange only for same product, I don't have a problem with that re: defective.]
