You can buy them at Wal-Mart online and if you have them shipped to your local store and pick them up there the shipping is free.

They are only $49.84 right now.
I got mine on ebay from someone fairly close that I could pick up from and I think I got the other one on Craig's list. If you don't have to pay shipping you can usually get a pretty good deal. You will love it! Good luck to you.
