Save yourself the $6 and go to walmart.com and use the store finder. You can search for just 24hr walmarts, supercenters, etc. It will even give you directions to the store.
Because in Wisconsin it is illegal to sell items in below cost, the prices for almost all blitz items are higher. The RCA TV is $699.97 on Friday in Wisconsin. I don't know about the other states where prices aren't valid - but it's probably the same.
