Ah, EBGames...
The one time I decided to take the chance and order two used games (Shadow Hearts and Super Monkey Ball 2), they both arrived full of scratches which rendered both discs unplayable (Shadow Hearts would freeze up the second the first battle started, and you couldn't make it past the mode-select menus of Monkey Ball). I enclosed a very polite note when I returned both games to them, requesting that if they were unable to find any replacements in working condition, that they would refund my credit card.
... A few weeks later, I got another package from them. Two copies of Shadow Hearts, both beaten to hell. No Monkey Ball 2 in sight. Okay, now I was confused. One lengthy phone call later, it was agreed upon that I would be refunded for both games, any shipping costs I had incurred, and a $10 voucher for my troubles.
Needless to say, I only buy new games sight-unseen online now.
