so far so good!

After reading several negative reviews, I was suspicious of the low price offered by Autoplicity but decided to try them out anyway. Much to my surprise, the belt for my car shipped immediately and arrived 2 days later via ground shipping from half way across the country. I was very pleasantly surprised with the speed of service and got my parts for the lowest price on the internet. A+!

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

Looked everywhere for a good price on Warn locking hubs, they were the best price around. Shipped right away.

Everything went good, order shipped out the next day. The prices were good but the shipping cost was way to high $25 dollars for 2 head gaskets and some bolts oil pan bolts.
