Found everything I needed. Product was delivered in a good time frame. And everything fit and worked perfectly.

Easy to find part needed.

I ordered these tires for my sons truck and then received an email stating that they couldn't fulfill the order. I then emailed them with my concern and they apologized and more or less said they would check it out. Before anyone got back with me about my refund I received an emailed that the tires were being delivered. Then the delivery truck was in my driveway with my purchase a day earlier than I was originally expected. I was very excited because the tires were a Christmas gift. Santa pulled this one off!! Thanks to Autoplicity.com we will be using this website again!!

excellent expierience both times..

All good, next day delivery

Easy so far. Hope for fast grounds shipping

Great fast service

Good comunication best prices on the web

Easy checkout. Easily found the part.

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!

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.
