Good service good prices

Great experience from start to finish. The information of when the tires shipped was very helpful. Thank you autoplicity for my new tires at an awesome price!

Easy enough... we'll see if it arrives.

We’ll see how it goes . So far so good .

My order #4383 was fulfilled quickly and shipped in a timely fashion. The price was super competative and the web site is user friendly. I will be back for more I'm sure! Shipping should be free for orders over a certain price, say $50?!?!

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

Great price and received item in a timely and in great condition. Will definitely shop here again!

Autoplicity made finding and ordering my parts simple and easy! Not only did they have the parts in stock and ready to ship, but they were also the cheapest BY FAR saving me nearly 30%!<br><br>The information that they had on the product pages was 100% accurate unlike other car part websites.<br><br>Autoplicity has made a customer for life!

They beat everyones price on-line and in town and it only took ten days to get my tire delivered to my front door I will shop with Autoplicity again I have told all my friends about the low price already Thank You

The order number 15547 tailgate lock fit perfectly. The shipping was very fast, ordered on Tuesday, delivered on Saturday. Will order from again.

The web site could use some updating or either there is a Glitch somewhere. I had to call to check on my order but it was already being shipped. They were on he ball, I just believe they are having computer troubles. Autoplicity had the best price I could find On my Bully Dog. Thanks Again!!
