They had great email communication and shipped my items from order number 14199 very quickly. I was very impressed with how they handled my order.

Damn fast on the shipping and great price on the item a great place to shop

Great company to order from! Low prices, wide variety of merchandise, and quick shipping!

I was looking for a present for my husband, and Autoplicity had the items way cheaper than any other site. And then I messaged them to see if they had any coupons available, and I was sent a coupon code right away. I will definitely shop here again for auto supplies.

best price i can find. shipping scheduled only 4days after i order. haven't received it but looks fast.

Great prices, quick ship thanks!

This was my second order with Autoplicity. The first order I had to call to get an update, but just happens the part was out for delivery the day I had called. This second order went without a hitch! In both cases, shipping was fast and the products delivered at great prices, not to mention some of the best prices on shipping. I will definitely look here for my future parts needs!!

i was advised by all internet sources, and the manufacturer that the part i needed was out-of-stock and discontinued, when i used google shopping, autoplicity not only had the part but they were the most reasonably priced! my order was delivered to my door in 3 days. color me a satisfied customer, and yes i will used autoplicity again, soon!

Autoplicity has really good service. They give you such good prices and yet they're still willing to give you discounts on your purchases. They emailed me a day later after purchase with shipping number. I would recommend them to anyone!

The order process was fast and easy. I was able to determine the part I wanted with the help of their sales department. I purchased my H&R lowering springs for less then I could find anywhere else and I also got a great deal on my EBC Green Stuff brake pads. The following day however i noticed a descrepency in my shipping address in the confirmation e-mail they sent me. After being dicsconnected multiple times and at least 6 seperate attempts to reach the shipping department i was finally connected and assured that the information that they had was correct. It did seem like a waste of 45 minutes but at least I know that the parts are going to be delivered to the correct address.
