I had a great experience.

Great price, free shipping and no tax. What else can you ask for!

After shopping around at my local auto parts stores and not liking what they had in stock I decided to go on line and BANG found Autoplicity.com and they had just exactly the black finished lug nuts that I was looking to give my Trailblazer SS a different look with the stock wheels, 5 ⭐️ 's and definitely will recommend them, thanks again Autoplicity.

Quick and easy. A bit heavy on shipping and handeling but what the heck

Part was easy to find and check out was super fast.

Got my products in a timely manner and they were exactly what I ordered. Will be shopping with Autoplicity in the future

Don’t know yet. I have not gotten the product

Parts were great but we paid for 2 day delivery and told by an employee we would get them on a Thursday but they didn't come until about 3pm friday

Great Price! Fast shipping and processing! Cant ask for more! A+

Great price and fast shipping, beat auto anything by a mile.

Prices are comparable to other retailers. And they have items in stock that others were saying it would take a month. Fast shipping and great communication. Thank

Great price and fast shipping! If your looking for quality brands at the best price available!!<br>

Wow ... they not only have the best price ... but also ultra fast shipping ... the really have great customer service too .. i like that they have live chat.

This site was just like shopping at a real store. It was easy to make my order and I was able to do it on the go on my smartphone which is important to me that a site is compatible with handheld. Bravo

Absolute lowest price on the web. Correspondance was great letting me know every step of the purchase and shipping process right up to a tracking number.<br>Ordered Tue. got tracking number Friday ... great job great savings.<br><br>I highly recommend doing business with this fine company!!

Ordered and received an Autometer gauge at the best price I could find. Received the package within 3 days well packed. I have not hooked up the meter yet. But it looks fine and is factory packaged.

Great product at the lowest price with fast delivery...what more can you want! Highly recommend.

I'm happy with my purchase and the service I received. I gave you guys a "good" rating instead of "excellent" on shipping only because I hate FedEx and would like to have another shipper option during checkout.
