It sounds like they are a large distributor that sells on the wholesale level. A suggestion is to call them and find out who they sell to, or want to sell to, and buy from them. As soon as you find their customers you can buy what you need. Some of the guys at the forum that work in the automotive industry or anyone with a wholsale licence in the states might beable to purchase from them.

I plan on doing the same thing here in Germany. I have found a distributor from them here also.
