Do you know if their Customer Service or Technical Support is in-house or farmed out, way out?
I doubt it and would concur with joemike's conclusion.
Separate from not being able to get technical answers, I'm really ticked about the bait and switch where they post a very specific deal for shipping but, when you place an order that is triple the requirement for the special rate, they say: "Oh wait, we have some rules that we did not divulge. Too bad."
