Excellent

1st time

Service was fast, shipping was fast, price was very reasonable. There was a problem with the item and I am contacting them today about it. I will let you know how it goes. The keys do not fit one of the locks.

first time on site .was easy to figure out

Great pricing, free shipping, and great product!!! What we got was better than OE for 1/5 the price! Thank you!

Autoplicity has the lowest prices. My new shocks were shipped within 24 hours with UPS Ground tracking#. Although I was expecting a closer warehouse than the San Diego one for my product to ship from (I'm in CT), I would still rate 8.5/10 stars.<br><br> The prices were so low that I ordered struts the next day so that I could take advantage of the MONROE rebate by ordering a full set. My MDX is sitting pretty and riding smooth once again. Thanks, Autoplicity.<br>order#8137 & #8177

Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!
