Excellent Customer Service!

I let Rock Auto know that I had a problem with the master I bought from them and within about a half business day I got a reply back from "Dan":

Thank you for your email.  I am sorry to hear about your dilemma and apologize for any inconvenience.  So as not to inconvenience you further, we will not ask you to return the failed part.  You may dispose of the part as you wish and we will simply refund your PayPal account within 48 hours.

Well that's more than I expected and saves me a few bucks in shipping. I have a new Raybestos Pro Grade on the way, so next weekend I should be able to swap it out.
