I was. Was a Rock Auto customer for years, made many purchases over last 10 years. This last experience was the one to award Rock Auto with losing yet another customer. Ordered 2 smaller emissions parts. Both fit in approximately 5"x5" box. Paid extra for faster shipping as I needed. Both showed in 2 days in one box, sealed with rock auto tape, so no funny stuff done by shipper. 2 Ac Delco boxes packed, but one box was empty. How someone could pick up/ handle a box and not know understand that it's empty is mystery itself. Years ago you could call and get problem figured out. NOT ANYMORE. They almost proudly announce on the phone that they keep prices so low by eliminating customer service via the phone. Try telling a computer that a box was empty, or to send me another immediately, as I paid extra for shipping. The more I tried, the angrier I became. Even Amazon in their quest to overtake the world has human interaction when you need customer service. That old saying Grandpa always said "you get what you pay for" rings so true, especially with Rock Auto. They seemed to unfortunately decided to take the ultimate greedy road as the choice for how they run their business. Buyer Beware! As long as everything goes good, and your shipment is correct, you will be happy. I was. But when it goes bad, (and it seems it goes bad at the worst possible time) it gets real bad when you are led like cattle into a generated flowchart with general and nonsensical questions that they force you to answer. At the end, you actually got the feeling that they really couldn't care less about your problem. They just want to know if you want to return it, or get a refund. It's a very empty, frustrating feeling. But. It is all in the wonderful name of saving us all money!
