So far so good.

Shipping is expensive

First time buyer and couldn't be happier with the service and follow through! Great Job Autoplicity!!!

I chose Autoplicity because they offered the best price on a specific part/tool I was looking for. Even with shipping cost, the total came out to below other online retailers (Amazon, etc.). My product shipped within the day and I am eagerly awaiting it!

This was the first time I'd shopped at autolicity. The site was easy to use and you guys had the best price by more than 20%. I'll be back the next time I need parts. Keep up the good work

Easy

Nice company...Products are significantly cheaper than others and fast shipping.

the delivery times are very very long but the price is right.

Great price! Super easy and I love that you give the ability to pay through Amazon.com! I feel very comfortable and safe using Amazon.

Excellent experience. Cheapest price I could possibly find, reasonable shipping cost (other people tried to charge upwards of $20 where I was only charged $14). Shipping was VERY quick. <br><br>I was slightly weary of ordering from Autoplicity as I had never heard of them before but from here on out they will be the first place I check. Could not be happier. <br><br>There is nothing that could have made this experience more enjoyable for me.

quick and easy! what more can i say?

Great website with very quick response time and fast shipping. Product arrived as described, however packing fell short of my expectations as manufacturer's box was taped up and components were jarred around during transit causing some pieces to be scratched. Overall, would certainly do business with the company again due to flawless customer service.

Two words easy and good deal
