No complaints. ordered a BAK Industries Truck Bed Cover BakFlip G2 for my Honda Ridgeline on 1/11/12. Package was shipped on 1/13/12 and arrived 1/18/12, delivered undamaged. <br><br>Autoplicity was cheaper than Amazon by about $40 (after shipping), and I didn't need to compromise on service. I would definately use them again.

Had the part i was looking for.

Ordered Borla headers 17216 that was lowest price on internet. Shipped fast at a fair price and arrived in good condition. Communication from Autoplicity was timley and accurate with tracking number. I would not hesitate to order from them again.

this is a great deal on a set of bedrail caps

Easy to use site, if the parts are correct I will upgrade 4 to 5 stars.

Easy site to work with, good representation of products.Extremely fair prices.

Great priced product

Quick and easy to pay. I used my Amazon account

Spoke to auto tech to see if sold in sets of two, he said yes. Placed order. Very easy. Thanks! After I received order, found out from the tire company, I only needed one box. Returned the other box. Now I found out, it is the wrong part for my car. I

Quality products, reasonable prices, product was delivered as promise, part fit perfectly. I would definitely put this organization in my top 3 best .

Great service, best price available online and realistic shipping costs, Ordered 5PM Friday, shipped Monday , received Tuesday end of day. Beats driving to the local store. Highly recommended !!<br><br>RS Larchmont NY

Best price I could find on Thermo-tec for the Corvette! Real quick ship too!!

They had the best price anywhere on the items I ordered(Recon Lights). Prompt emails and accurate tracking via UPS shipping. I'm pleased and will order more items now that I know they're "legit". Thanks Autoplicity!<br><br>Nick C.
