I purchased an extend-a-truck on autoplicity.  It was the best price on the Internet.  Autoplicity beat amazon by approximately $30.  I received a confirmation it shipped the following day.
Great pricing and customer service. Item shipped on time and with no complicaitons. Best pricing on the internet that I could find. Great seller.
Great service, best price available online and realistic shipping costs, Ordered 5PM Friday, shipped Monday , received Tuesday end of day. Beats driving to the local store. Highly recommended !!

The ordering process was simple and user friendly.  The pricing was the lowest I could find for a brand new AMP Powerstep for my Ford F150.  The tracking number was provided and the item is scheduled for FedEx ground delivery in 3-days.
