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.

I would definitely recommend Autoplicity. I ordered Thule bike racks (THU-518), and the products arrived in 2 days in perfect condition. Plus the prices (along with free shipping) were the best on the web.
