But Rock Auto gives us a discount.

 

RockAuto is not a store. It is a trade association like Amazon or AliBaba. They ship other vendors products, that's why inventory varies.

 

I believe the discount is 5%. There are many forum sources for the codes. I always use the code when I order.

Donbrew, a big difference between Amazon or Alibaba and Rock Auto is that you can call Rock Auto and speak to a live person that actually knows about car parts. I've never had to call but my dad did twice. Good experiences both times.

 

But they are a vendor on this forum
