Rock Auto owns no warehouses and has no inventory. They are a drop shipper. For their regular inventory, RA mostly uses Auto Value and Parts Authority warehouses, which supply independent parts stores, while some parts ship directly from the manufacturer. Google the return address of your Rock Auto box next time Most of their wholesaler closeouts come from Ultra-Power in Sugar Land, TX. Their site is surplusparts.com

Do you go to the dollar store expecting the same level of quality as you would a name brand store for the same product? NO, that is because the dollar store specifically searches suppliers of out of date products, shipping damaged, etc. They don't pay full wholesale for their stock, which means you don't pay full retail for what they sell. RA is no different. Be informed about what you're buying and buy with caution. RA is only interested in the sale, not product quality or customer satisfaction.
