No complaints. ordered a BAK Industries Truck Bed Cover BakFlip G2 for my Honda Ridgeline on 1/11/12. Package was shipped on 1/13/12 and arrived 1/18/12, delivered undamaged. <br><br>Autoplicity was cheaper than Amazon by about $40 (after shipping), and I didn't need to compromise on service. I would definately use them again.

Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

Great Prices and fast, fast shipping. I will definitely do business with them again.

Ordered some fluid coolers for a project, great price, easy website, FAST shipping!

Bought a sparco steering wheel. Best price on the net. And shipping was very fast. Thank you
