I reciently ordered some spark plug wires from Autoplicity and I must say it was a great experience.  The shipping was fast and they had the best price I could find.  I will def order parts for my truck from them again.
Ordered Sunday and recieved product Tuesday .. What more can u ask for? Great Seller!
Easy and fast
I am very, very satisfied with my order.  I ordered a Tonneau cover.  It was a 35 lb. package and there was NO shipping cost to me.  Plus it was received 3 days after my order.  I searched many other websites and Autoplicity had the best pricing.
