My order #4383 was fulfilled quickly and shipped in a timely fashion. The price was super competative and the web site is user friendly. I will be back for more I'm sure! Shipping should be free for orders over a certain price, say $50?!?!

Autoplicity made finding and ordering my parts simple and easy! Not only did they have the parts in stock and ready to ship, but they were also the cheapest BY FAR saving me nearly 30%!<br><br>The information that they had on the product pages was 100% accurate unlike other car part websites.<br><br>Autoplicity has made a customer for life!

They beat everyones price on-line and in town and it only took ten days to get my tire delivered to my front door I will shop with Autoplicity again I have told all my friends about the low price already Thank You

Ordered a couple K&N oil filters for my bike and they were the cheapest by far. The order arrived quickly and exactly as promised. They kept me informed of the status all the way. i would definitely buy from them again! Ed

Great selection, prices and very fast shipping! I will return!!
