Placed order on Sunday and received shipment on Thursday. Haven't installed items yet but boxes are in good shape. I'm satisfied with the transaction.

My first experience with Autoplicity has been great. One of the best prices I found for the item. Too, the company is not secretative about itself such as another parts discounter.<br><br>Autoplicity is now "bookmarked" for future purchases!

fast and simple. I would have only liked to see the shipping options before the submission of payment
