Rock auto issues....

I don't think there is a Rock Auto central shipping center. My understanding of how they do business is they are merely a marking center for other suppliers -- they process your order, take your money, then pass the order on to the supplier. It is up to the supplier to ship the product. That is why you get so many listings for the same part, and at what is sometimes a great price, and lousy other times. If you contact Rock Auto they'll probably light a fire under the supplier's wallet pocket.
They've got a few warehouses, this one happens to be in California. There's one of their warehouses not too far up the road from here on Highway 301 and State Road 60. Problem is they're completely online only, they don't even have a customer service number! The website doesn't even give you a way to leave a note for someone to see if the thing even got hidden underneath a box, or thrown in the garbage, or a part-time temporary day labor crew stuck in their pocket or whatever... last time I had an issue with them they wouldn't let me return it until I took possession of it I contacted FedEx and told FedEx to turn that **** around, Do Not drop it off at my house! That worked! lol different deal here
