Interesting reply from RockAuto

I split my buying among 3 local stores (Car Quest/Advanced Commercial, Napa, and an Auto Zone that's a last resort when others are closed) and Rock Auto. Always been happy with the stuff I picked, and I've returned a few things with no trouble after talking with them. The Absolute worst place was a Mopar specific NOS parts place. That escalated to a claim through my credit card before they relented and credited me in full with shipping.
