Don't mean to thread crap but they also have (online only though, I think) the following 24" case that has wheels and a telescoping handle and is pretty well discounted at $30 down from $50.
Picked up two of the 21 inch cases and one of the 24' with roller wheels and retract handle at the Waldorf store. They have a little over a dozen left of both sizes... Great deal on both; $19.99 and $39.95 Thanks to the OP for the heads up...
I saw these during Christmas for I think 30. I told my wife no when she asked about getting for my as a present for the tree. I wasn't really sure about their quality but 20 and maybe even 15 now???? I might need to visit!
