I placed my order for an Autometer Shift Light and it was shipped the same day. I was provided a FedEx tracking number in the shipping confirmation email.

Very easy to select what I wanted to buy and the check out process was simple and quick.

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly.  The price was the lowest that we found on the internet or in any of the stores where we looked.  We were notified by e-mail as soon as it shipped.  We will definitely shop this site again.
