Out of all the websites I've used to find my item, this was the lowest cost, and I'm so happy that I found them! Keep up the great work guys!

the only place that had my part

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!

Great price

I used a coupon code that was said to give me free shipping, I don't see any charge fire shipping until the very last page, then $10! Wow lucky I really need these

I'm always had a great experience!

Good web store front. Makes Parts Geek look like the trainwreck it is.

Shipping it a little high.. I think offering different shipping methods for lower prices would be nice. Other that that the transaction went as smoothly as possible!

Great priced items. was WAY under what others wanted. shipped fast also. A+ seller. I will buy from again.

easy

Smooth transaction

Real easy. Thanks

Outstanding
