ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Why shop on Ebay, when there is Autoplicity. Cheaper prices than Ebay, Faster shipping and good return policies.

My name is Doug Raber and I tell you the truth when I say autoplicity is a great site to shop for auto parts. The prices are low and the customer service is excellent.

Will use Autoplicity in the future. Just dont fully belive the 24hour shipping. I ordered 2 parts that where listed as in stock and it still took 3 days to ship. When I called customer service about my order agents where rude and stated there shipping is based upon 24 "buisness" hours.

Great sources,very easy ordering,outstanding prices, <br>I will always check their prices first !!

Good customer service.Very friendly persons in service dept as well. Will shop here again.

First time I've ordered from Autoplicity. They had the cheapest price, I found online. Shipping was quick also. <br>Thanks!!!

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

no problems at all. found what i was looking for at the lowest price i could find
