I have just ordered, please check back for a review after I receive shipment.

i was very surprised at how easy to use the Autoplicity website is. i had made an wrong entry in the shipto address and the customer service people were very helpful to get it corrected. I found the best price online on exactly what I wanted. Great site, great service. i will definitely shop here again.

I could only pay with my Amazon Visa card on file, but I have money/credit in my Amazon account,maybe Amazon will use the other funds?

Great
