Ordered the item Sunday 4/15/12, item was shipped out that Monday, got the tracking number Tuesday to find out the item is already in my state! Scheduled delivery is Thursday, super impressive on the shipping, best price anywhere by quite a bit! Very satisfied and recommended.

Parts were actually in-stock unlike every other retailer I tried. Quick shipping too.

Found Autoplicity through price searching. Best price, easy to navigate site, quick service. Bookedmarked for future use!

cant say much, just placed order

Easy transaction. Shipped as promised thanks

So far I am happy with Autoplicity's order status updates. I like when shipments are in process and with the updates I know progress is happening. When an order doesn't seem to be moving along a customer wonders what the hold up is. Well so far I don't have to wonder which makes me more patient in waiting for my order. Thank you, I will explore Autoplicity's website for more cool stuff for my car.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Totally amazed. It made it to my house in TWO days AND they had the LOWEST price. I was nervous cuz ive never heard of them. order number 4463
