Ok just got back from Wally World and heres the deal they are the full 45min episodes (1 hour-commercials=45mins) they include a bonus dvd with the Surviving Urban Disasters special but for some reason they dont include the Behind the Scenes episode. For 16.46 plus tax this set is a really good deal.
I also got one at WalMart. What a great deal! Three DVDs for less than $17. My boys are glued to the tube watching the episodes.
Buy one, you'll love it!
