My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Ordered Lucas gear oil and have to say the service is great and delivery was very quick. I will recommend Autoplicity for quality yet affordable prices. will do business with again!

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.

Amazon pay nice
