So far so good, we'll see how the shipping goes. "Ground shipping" is vague. UPDATE: Received everything in a timely manner. Might be ordering more!

They have the best prices and fast shipping too.

Very quick and easy!!

Great price and fast shipping!

Best price I could find! Great customer service kept me informed through the whole order process to insure acuracy since it was being sent directly from the manufacture. Recieved my order in good time, right parts and no damage. Overall very satisfied and will be doing business again in the future.

Very competitive low prices and great product selection. Will definitely look to this vendor when purchasing automotive parts in the future.

Great prices and FAST shipping!! Definitely will buy products here again!

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
