Well, I bid on an auction for SMT: DDS 1 that would have ended in about an hour, but I got outbid about an hour earlier, PLUS there was an update on the 19th by the seller that the item was "stolen" *cough* unsatisified by the top bid price *cough*, so it wasn't happening anyway. The guy who outbid me won an auction for a copy of SMT: Nocturne for less than $7.
Like one of the above posters mentioned, looks like a good deal for some stuff/sellers but not for others.
edit: It looks like there isn't much bidding going on at that site at all, anyway.
