hey had what I needed at a low price and were easy to deal with.

Great service and fast shipping. They were the lowest and best price I could find on the internet. Thanks!

Merchant agreed to resolve the issues. Items were received after 3 days and received the lowest price.

I ordered my Auto Vent Shade bug deflector 18174 on Thursday afternoon, June 14, 2012, and had it on my front porch by Tuesday, June 19, 2012. I thought that was fast shipping, especially considering there was a weekend involved. The price was also very reasonable. I am anxious to install my new bug deflector. I will be turning to Autoplicity in the future for my auto needs. Great Job Autoplicity!

Ordered Thursday, shipped Monday... guess all in all we can't be disappointed. At least they had them in stock.

I have used them a couple times. Always seem to be one of the lowest prices on the internet and pretty quick turnaround on shipping. If you live near Los Angeles, they have a warehouse in Cerritos, so things arrive real quick once they're shipped.

I ordered thermo tec express sleeve heat suppression for my honda s2000 through autoplicity.<br><br>I ordered it on 07/06/2012 and recieved a day later,very fast processing. Order came well packaged and competitive pricing.

I placed an order 12/5/11 and recieved my order before 10am the following day. Very fast, very easy to use and the best prices I've found on line.
