I placed an order and after checkout was completed these morons wrote me an email 2 days later stating that they apoligize but one of the parts was not in stock in the warehouse they thought it was. So if I want the part I would have to pay an additional $17.00 to have a $16.00 part shipped. How about taking some responsiblity, you screwed up by not keeping your website up to date. I will never use Rockauto again!!!!!! That cost should have been eaten by YOU, now you lost my entire order and any future orders, I hope the $17.00 was worth it. Not exactly a good business model.
