Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

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

Great price for the item, almost half off. Good website for auto parts

Easy and safe

Did a very good job at keeping me updated and letting me know when my product was being shipped. Only took a day to get out from the manufacturer. Very happy with the results. I will be back.

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.

Now problem with Autoplicity---you contact them---they respond--Thanks

Greatest web site i have been to in a long time. Great products, affordable prices, and my item wa shipped fast. I would highly recommend and i will be back.
