Smooth and uneventful so far.

Product information was accurate and as advertised.

Overall great shipping info could have been a little sooner not after it was already almost here

Thanks for your order

It's been a good experience so far but I have to return the part it ended up being the wrong one on my behalf so we will see how easy the return process is

easy ordering

A few items could have a better description.

cant wait!

survey after

Easy to order we will see when product shows up.

Half price same item and brand than a dealer

Excellent price and fast shipping. Product showed up as described and timely.

Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

My only complaint is that the site couldn't identify the size wheel center caps I needed by vehicle type. I had to measure the center hole on my wheels, lucky I'm a tool junky.

Thanks

Autoplicity has the lowest prices anywhere..Customer service is always there to answer any question..Shipping was also fast... Definitly will be doing more business in the future...Thanks Autoplicity !!!!!!

extremely simple process

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.
