i looked for a week to find the best price and autoplicity had the rest beat and they didnt charge me an outragous shipping and handling fee.... will use again...

Very good and easy experience! Items shipped out quickly. Definitely will do future business here.

Good

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

Utilized customer support for question on particular item. Phone answered immediately, consultant answered questions and I was able to place order immediately. This second purchase was due to the initial experience. Will make future purchases from Autoplicity.

First time that I have tried Autoplicity. Best price on the brand/part that I really wanted. Fast turnaround, and they have great customer service. Will use again. Highly recomend!

The roof rack I ordered came quickly, shipping was free, and far cheaper than anyone else.<br>This was my first order, and I will order again.
