Autoplicity had by far the best price I found for the part I needed. My order shipped promptly. I recommend them to all.

Excellent price on the product and shipping! Ordered on Thursday night (after they closed) and they were shipped out Monday!

Good company to deal with, will gladly do business here again.

This was my first time shopping with Autoplicity after finding them on a froogle.com (google shopping) search for low priced Hawk brake pads. The shopping experience was great, checkout was smooth, and the prices were unbeatable. I only give five stars for perfect experiences, and this was almost there. My only gripe is the order was placed on Friday and not shipped until Tuesday, with the shipping confirmation email going out Wednesday. I guess I'm spoiled by Amazon same/next day shipping and instant notifications. It would seem the notification issue could be fixed easily... Thanks Autoplicity - I'll be back!

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

delivery was on time and quick, ordering was simple product looks as it should be,great.

Unbeliveable customer service and super fast shipping. I had a question about my order and I was able to use the online chat function to instantly connect with a customer service agent that was quick to answer all my questions regarding my order. I am very pleased with the level of service I received not to mention the great price they offered on the item I purchased. I will be sure to continue doing business with Autoplicity for my automotive needs. Thanks so much. A+

Great prices
