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.

So far so good...

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!
