Great prices. Fast shipping. Huge inventory.

Great product. Fast shipping. Great and easy to use website! The air filter I purchased <br>From them cost $20 less than it was priced for at other competitors! I am very happy with the price.

great chair for pool table area or any man cave

I needed two fairly expensive parts for a project. Naturally, I shopped everywhere before deciding on where to purchase them. Autoplicity had the best price on the carburetor. I continued shopping around for the alternator, and ended up right back at the Autoplicity website, because they beat everyone else on that price also! And I don't mean by a few dollars! HUGE savings! Thanks Autoplicity! In the words of Arnold, "I'll be back!"

Super easy + best price on the web. Very pleased am I.

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

ordered a K&N air filter, pretty simple. good price, timely shipping.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

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.
