It is available at Overstock.com in both DVD and book format.
Right--that's where I ordered my DVD from and it is on the way.
It's available at Wal-Mart. It's a very well-done movie, although I think they must have used some third-world production house to burn the DVD, because it won't play on some DVD players, and it has this awful smell as if it is actually burned when you take it out of the box. I thought it was just a bad copy I got, so I took it back, and the replacement that Wal-Mart gave me was the same way. I did find a DVD player to play it on, though, and it's worth seeing, for sure.
It is also available at Blockbuster,BestBuy,Circuit City,Ebay,Overstock.com,Sam's Club and a few other places.
