Rockauto discount

I get these discount codes every once in a while from rock auto. There’s no limit on how many people can use it. It’s 5% and ends 03/29/2020.
Returning damaged stuff is the major issue I’ve had. Ordered some tensioners for Shannon’s explorer back around Christmas and one of the threads ended up being bad. They wouldn’t swap it out unless I bought another then it took forever to process the return.
