Bill Zebub's movies are all over the Internet as well as fine stores. If you don't see them at your favorite place to shop, ask the clerk to order your movies of choice via www.musicvideodistributors.com (most stores buy from that distributor)
Almost ALL of Bill Zebub's movies are available from bestbuy.com If you don't feel like buying through the Internet, just cruise into your favorite Best Buy location and tell one of the DVD department employees to order your copy. The employee will go to a computer, verify the title with you, and order it. It will arrive in the store within a couple of days for you to pick up.
