My buddy is the asst manager at a local retailer. You usually get your shipments the day before you put them out (new releases I mean) so they had them already and they were all tagged and ready to go. I used to run a music store in PA, so I know the drill. If you really want a stab, I got it for $20 too.
BTW, the CDs have two CDs worth of music, the DVD only has the first one and a bunch of gallery stuff and probably some vids. They're both $29.99 retail.
