AWESOME PRICE

So far its been fast and easy. I only hope the box comes undamaged. It looks like a nice box. Arrived with a little cardboard damage from UPS. The toolbox had some minor dents that I successfully pounded out. Was no fault of yours. Thanks.

They had the best price I could find, anywhere, for Royal Purple HPS oil (and I spent hours searching). I ordered a case on Sunday night and it arrived on Wednesday (standard shipping) from half-way across the country. For standard shipping, that's pretty fast. They must have send it out early Monday morning, at the latest.<br><br>I'm very satisfied with my experience, and I'll definitely be ordering from them again, when I need another case of oil.

Very easy. It wasn't my first order and it won't be my last for sure.
