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

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!

After searching Google Shopper for a Thule 45058 roof rack kit, I ran across Autoplicity.com was, by far, the lowest priced vendor for the product - so low that a local retailer offered to take 20% off their MSRP price but it still didn't compete with Autoplicity.com's price. Purchasing was a breeze and I look forward to receiving the rack soon.

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.

best price around and quick order placement

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.
