Totally happy with my order. I'm amazed with the product.

excellent service A+++++

So far good price.

I ordered some hubcaps for my Chevy Aveo because one of my old ones broke. Standard shipping is a little high, but that is expected. It only took a few days for them to get to my house, so I was greatly satisfied with my purchase.

Item arrived on and was correct part

Super fast shipping, great products. will order from again.

I was very excited

Works great

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.

slight hiccup with payment, but paypal triumphed over Amazon!

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
