I have a small auto repair business I used to get all my parts from autozone. if a customer can wait I will order from rock auto. autozone has gone crazy with their prices. their stock proves it. a few years ago it was 50 dollars a share. its now 800. I get the same part same mfg. for 80 to 100 percent cheaper from rock auto.
