I've used Autoplicity before and I love their excellent prices and same day shipping!

I recently ordered the clover patch for my new 2012 Jeep Wrangler. The price for Autoplocity was the best I could find on the web and their shipping fees were also very affordable. I received my confirmation emails promptly and I was able to track the status of my order very easily. I enjoyed my experience ordering off of Autoplicity and I am likely to purchase additional products for my jeep off this site.

Had to call technical service for a question. Hold time was very long but once connected the technician was friendly and helpful.

This was my first time using Autoplicity.com. It was an easy site to navigate. They had everything I was looking for in one place. The prices were reasonable and in the ball park for what I was looking to spend. I received confirmation of my order immediately and an email when my items were shipped. I will definetly shop Autoplicity again.
