Good Job!

Fast easy great prices. T hanks

Very easy, we'll see when it arrives. GOD bless

the only reason i gave 4 stars is because you only offered one shipping way, also this is pricy.

There were some communication issues at the beginning. Some confusion about order numbers and shipping led to a couple days of going back and forth with them. In the end, they made every effort to make sure I was satisfied and that my order was complete and correct. Extremely cheap price, I bet I saved almost $100 on 4 EBC rotors. My only complaint is it took almost 2 weeks for shipping, but it did ship directly from the manufacturer so I can't say that's entirely the fault of Autoplicity.<br><br>Order #28295 on 08/26/2012

Unbeleively fast shipping. I ordered on a Tuesday night, and it was delivered to my door by Thursday. Plus, the item was the cheapest with shipping on the web! I will most certainly be doing business with them again!

Great product. Good communication and customer service!!!
