Thanks for the heads up! I loved the demo, and have been waiting for it to hit a reasonable price.
I've never seen this anywhere for $20, so it's a deal for me. (I don't and won't shop at the Walton's Mart though.)
Good grief, I get Amazon Prime for my new Playstation Portable, and two days later start using it constantly. The component cables and now this! I always tell them to group stuff together though since I don't want them to have to spend more on shipping just for me maybe getting one item a day earlier or something silly like that.
