They had an item that was somewhat hard to find at a reasonable price. Glad I found them.

The best prices and fast shipping!

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.

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

great service, even better price! Would recommend Autoplicity to anyone.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.

A+ part as advertised, quick shipping.
