Simple and easy

Easy to use website and discount offered on shipping. Thank you.

Easy shopping. I like the payment options of PayPal or Amazon.

good

Ordered a Thule ski rack. Best price on the web. Prompt delivery as promised, however, did not get shipping email and tracking no until after delivery was already made. The customer service that I experienced trying to get info on delivery was less than desirable. Four stars o ly.

Great fast service!!

Liked the discounts

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.
