Shipping from Dr. Diff in USA?

Hey All
I have some suspension parts in my cart but before I purchase I wanted to ask if anyone has purchased from them? They offer several options for shipping and my previous experience with FED EX is that I was raped over "Broker Fee's" when buying in the USA. I have been told to insist on USPS to avoid such fee's.
Anyone have experience?
Advice needed and appreciated.

Pete
