Not to be repetitive with everyone else's advice, I will say this: be glad it was only ~$10, and be glad he's going to refund your money. I know people that spend $25 and upwards for a single CD on eBay only to get a bootleg and not be refunded. I personally avoid eBay like the plague, so good for anyone willing to risk it, but you do have to be very, VERY careful.
