great prices, fast shipping

I ordered the Truxport tonneau cover for my Nissan Frontier. I am very happy with Autoplicity,they have the best price by far on this product,and they promptly sent me an email when it was shipped.....the ONLY thing I wish they would have done but didn't is to include a tracking number. I think the reason they didn't include it is that it was shipped directly from the manufacturer,but they did give me the tracking number when I called and asked for it. Overall a very positive experience

They had the best price on the internet! Fast shipping and repsonse.
