Great pricing and quick shipping. GREAT

Awsome service and prices,Thanks alot

Price was way below anyone else. Delivered on time and as advertised

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.

This store had a lot of products more than most other sites I looked at. The order was processed quickley and shiped the next day. I will use them again.
