That's why I don't buy from them that much.
I did buy a spare tire cover when the ex wife trashed mine. It was cheaper thru them with shipping.
The sell parts about 60% to 75% cheaper than the dealerships, but the shipping bumps the total cost either equal to or more than the dealer price.
The quoted dealer price on their site is correct. Make an order like you are going to buy then on the invoice page the part number shows up. Call a few GM dealers and give them the part number and there's your part
