US online...? ...retailer

Looking for the type sold in Australia made by Brackley Industries (not the single post or overlap type my searching has found from US sellers). This is the type of case that Paramount and Warner Brothers use on TV season sets like "Beauty and the Beast", "Birds of Prey", "Dallas Season 10", and others, which is the same size as a standard single DVD case, has 2 trays inside, and uses what I think is called an "M" type center hub. Shipping is so expensive they cost more than $5.00 apiece to order them from Australian Retailers.
