299 60 Gigs at walmart

I knew the 20 gig pro was 299 but my local walmart is selling the 60 Gig along side the 20 for 299 also.I asked the clerk about it and it was true .So is this just an oversite on walmarts part or what? Has anyone else seen 299 60 gigs out there?

its an oversite.  I would try and buy one if you can.  if you get it for that price sell it for on Ebay
