I was very impressed by Autoplicity's customer service and excellent pricing on brand name products. Also, they provided lightning fast shipping even as the holiday weekend approached.<br>As much as I want to see everyone in this world to "live long and prosper," I was especially pleased to deal with a company that did not export their customer service to another country. <br>I look forward to doing business again with Autoplicity.

Item shipped 5 days after order was placed. Worth the wait for the great price however. Order Number: 18722

I was shopping for a bed cover for my truck and found that autoplicity had the lowest price when I was ready to buy. After I placed the order, I got an email notifying me that my order was shipped and got a tracking number. Seamless transaction so far. Very happy.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

Very good

The best prices and fast shipping!
