I placed an order with the GMParts Club and aside from the insane shipping and fee, it took them over a week just to ship my item... not to get to me, but to actually create a shipping label. Wow, maybe I am just spoiled by other online retailers- but that was not very good.

 

The part may have been out of stock system wide, who knows.

I've been using the other big GM online parts wholesaler and while not state of the art, they've been pretty good.
