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 bought shocks for my Silverado. Very little product info given, I had to search part numbers on other websites to verify what shocks were for the front and what ones were for the rear. Also I would very much like to be able to ship to a different addres

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

The best prices and fast shipping!

GREAT PRICES AND COMMUNICATION!!!! HIGHLY RECOMMENDED STAFF AND PRODUCTS!!!!!

Item arrived in two days, item was at the best price available, great service will use again!
