Great and simple

Great

I appreciated all of the communication regarding my order that I received from Autoplicity. Following my online order I immediately received a confirmation email confirming my order and providing me my order number for tracking purposes. I also received a notification when my order was shipped along with a tracking number for the shipper. Once I received my order I received a final email requesting confirmation of receipt. My only modest frustration was the final email requesting confirmation then led me to a short survey requesting my rating for Autoplicity's overall shopping experience, delivery time, etc. It was only 4 questions so that wasn't a problem. My issue was that it wouldn't let me submit my review without leaving a comment in the "Comment" window - that should be an option not a requirement for submitting a review.

Best price seen on part.

Easy to use format. Didn't ask for vehicle engine size which may make a difference on proper fit.

Good prices

Very easy to fine product.

So far easy transaction....we will now wait and see how fast it is shipped and if it is all good.
