Overall great experience, I ordered on Sunday and got the package on Wednesday!!!

so for so good

very easy

Fast and easy!

Ordered the ARB 50QT fridge from Autoplicity b/c they had every merchant beat by more than $100. Very happy with the transaction and would highly recommend - best prices bare none. I called Auto Anything and was told they match pricing with most vendors - except Autoplicity. I can see why. My first order but not my last!

Great Price and fast ordering

Web site was clear and easy to navigate, the price was the best I could find, and the item was shipped promptly. I would recommend this retailer to anyone.

Super easy and Quick! Called Tech. Support to confirm my part selection/fit. Really fast delivery for coming from the east coast. BUT, Part was not as pictured. I actually purchased because of the BOSAL brand and the picture was identical to the one I nee

Autoplicity had the lowest price on the item I needed, shipping price was not out of line and item was shipped in the time frame promised. Who could ask for more.

Easy

Great site

Super easy + best price on the web. Very pleased am I.

Quick and straight forward. Good Job!

Same day shipping. Highly recommended!
