Target also has the 2-disc DVD for 16.99. I saw the weekly ad and it said "Exclusive calendar and bonus disc with Walk Hard STANDARD DVD." So I went down there because I wanted the exclusive bonus disc, and none of the Targets had the 1-disc standard DVD. One Target had only 2 copies of the 2-disc edition out on the shelf, so I asked the stockboy if they had the 1-disc version. He was a total asshole, when I asked him he looked at me like I was crazy or something and he didn't really seem to care anyway. He says that there aren't 2 different versions and the price of the 2-disc one is 16.99, even though I was sure that there were 2 versions since Best Buy had them. I thought that the 2-disc would ring up as 22.99, but after he scanned the UPC, it was indeed 16.99.
So it looks like this is an error on Target's part, the calendar is packed in with the 2-disc edition and the bonus disc is probably just Disc 2 of the set. Plus, the ad shows a picture of the 2-disc and not the standard one. I was hoping for an exclusive bonus disc with content unavailable anywhere else, but I doubt Target will get it since they don't have any 1-discs. Also, it seems like there was a distribution problem, seeing as how some Targets got so few copies and some got none at all. I got my copy at BB with the free T-shirt and hopefully I can get it price-matched tomorrow with the Target ad.
