I purchased a BakFlip F1 truck bed cover, they had the best price I could find anywhere. Their shipping process is very fast. I will look to buy from them again.

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.

Ordered a Rampage frameless soft top for my Jeep. Smooth as silk. Price was outstanding. Order was processed and shipped very quickly and top arrived as adverstised. I would certainly do business with Autoplicity again!

Quite shipping and awesome support. Definately going to do business again.

Best prices on the net! They had everything I needed at one site.
