SCORE!
So I called them this morning and inquired about the rear bumper (because their ebay store had it in stock) They confirmed they had stock, gave me 50% off and free shipping. Funny because I had to pay $30 for the valence and the front bumper, when ordering online.
Hopefully, they will be able to fulfill all the orders. I guess they can always drop ship from AMD, if needed.
Rear bumper came to $199.95!
