Easy shopping, however the confirmation from the warehouse and then the shipment to my home, took a week. For an overall product purchase it's fine, but if you have your car broken and you are waiting for the part, the waiting time is terrible.

Lightning fast service! Good prices.

AWESOME SERVICE,SHIPPING,AND PRICING..COULDN'T ASK FOR ANYTHING MORE!!!

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.

Autoplicity, was very easy to use, very fast, and an enjoyable experience. I would recommend to my closest friends!!
