I actually for the third time in a week had this happen on yet another disc. One seller offered a bunch of excuses which blamed everyone but himself for the wrong item. The others have yet to respond. Wanted to believe it was a simple mix-up but you're right troublezone - just deceptive sellers. I hate to think I would have to abandon Amazon Marketplace like I did ebay long ago. At least from what I hear Amazon is good about the refunds.
I guess this is the flip-side of the time the guy I ordered a Maiden remaster from, for little more than shipping, sent the Castle release instead.
