Took a look at the new gmparts dot com site, we will be screwed big time. There is a link for authorized sellers ie: E-Bay, Amazon, etc. Pick a part, any part. Search by zip code and find a dealer near you, one might have it for $100 the big wholesaler has it for $46.
Already had one call yesterday, customer wanted to make sure the part number he gave me was correct since he looked it up on the new site. Of course our pricing was off since the big gun wholesaler had it for a small percentage above cost. I was ready to say, "No your part number is not correct, use 1051515.
