Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them again.
PIAA stuff ships slow but good prices
Good company to deal with, will gladly do business here again.
As the merchant name suggests, the process of my purchase was straight forward and simple. I do not need anything else , so next time I will shop here again.
