I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

Best price, excelient communication, on time shipping, Great place to do business !!!!!!!!! Thank You!!!! JY

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!
