The best price on what I was looking for and fairly fast to get it shipped out considering it was drop shipped directly from the manufacturer. Autoplicity has a huge selection and I will definitely be back when ever I need other automotive parts.

Couldn't choose any of my other amazon shipping addresses as my method of payment showed no payment method for any other address so I had to take shipment to my main address and now I have to drive the parts to where I need them 90 mins round-trip plus t

Received my package today. Shipping was fast and it was about the best price I could find for my Cam. I'll buy from them again.

Prompt shipment, I got everything under 5 days even if part of my order was drop shipped (in stock items arrived in 2 days). Good communication, would do business again in a heartbeat.

I will definitely do more shopping with Autoplicity....great prices and quick shipments.

No issues at all and a very good price to boot. What could be better? Will definitely order from them again.
