Good comunication best prices on the web

Awesome dealer for auto-parts. Fast shipping and they sell good products at great prices! Bought set of club racing brake pads for $15 less than anywhere else on a Saturday and they were here the following Wednesday. I'm in Memphis and it was the week before Christmas. I was very impressed and pleased!

well see

Web site was clear and easy to navigate, the price was the best I could find, and the item was shipped promptly. I would recommend this retailer to anyone.

Thanks for the great service, best prices, and fast shipping!!!

I was searching around for a K&N cold air intake for my Tahoe. After searching Autoplicity had the lowest price hands down. I ordered on a Wed. evening, and it was on my door step Friday afternoon with standard shipping. I couldn't of asked for better service. The price was $100 cheaper than everyone else. I will be using Autoplicity again.
