I have only had great experience with Rockauto until yesterday. My billing and shipping address are different. When I changed the shipping address it took off my store credit. When I put it back on, it would change the shipping address. Customer service was no help and didn't seem to care. Very disappointed and frustrated. I have never had any other problems and would recommend them to anyone who just wants to pay.
