Bought a Husky trunk liner for my Civic. Autoplicity had the lowest price I could find, plus I received it in two days. Only problem I had was that their website had a problem with the part fit check. Although the description and part number was for the 2012 Civic, the part check said it would not fit. Had to wait until Monday to call customer service to verify that it would fit before I ordered. Would definitely order from Autoplicity again.

Good so far

Easy

Shopping here was a breeze.. Information was clear and helpful. I will definitely consider shopping here in the future.

Needs more info and better pictures.

good price

Smooth process and easy to follow instructions for checkout

Ordered a Thule Bike Rack from Autoplicity and was greatly pleased with the price. It was the best on the internet. There was an issue with the shipment of the item and some confusion but this was resolved in a professional manner by a customer service manager. Overall, I'm pleased I got a deal.

Had product I was looking for, price was right and shipping a bit high

received a follow up phone call within a hour letting me know that my order #5153 would be coming from a certian warehouse and about what time it will arrive...Great service!!!highly recommend

Order delivered in 3 business days, packed well, got exactly what I ordered, can't ask for anything more at this point. This is exactly how eCommerce should be done.
