Better keep an eye on any orders placed as Rock Auto will appear to have all items in stock, and then not ship your order over one item found short (ordered major A/C components, returned from a convention to find parts not delivered, Rock Auto found they had only 6 of 10 O-rings, so did not ship anything!). Did not expect to have to watch over them. Any competent seller should look over their mistakes and consider what is a reasonable solution that will be best for the customer. Holding a major order when you find you are several o-ring short now hurts my customer. I could find an O-ring locally, if I needed more than the six they had in stock! But now I have to source major components to get this car completed. Also, another concern: shipping will eat you up, as they have parts in so many locations, that you will have multiple ship charges for misc items to complete a repair. Expensive. Time consuming to correct when you discover this at checkout.
