They were Very quick and i was very happy with the service i got!! 9-10*

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Great customer service, item shipped quickly. Very satisfied.

Best price on Toyo tires I could find anywhere! And the shipping was $0.10 on the dollar compared to all the other tire retailers I checked. Definitely will order again from Autoplicity.

Great prices and fast shipping! What more could you ask for?

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
