Great product, fast delivery.

Delivery truck was delayed for one day do to maintenance issues. My order arrived before lunch the following day. Delivery guy was very nice and called ahead of time advising me what time he would be at my home. My order was correct and perfect!

Simple, quick, in stock .... and fast shipping ... AAA+++

Product was as described, great price and reasonable shipping cost. Shipping was also very quick.

Quick shipping on my order. Thanks

Wow. Ordered it on a Wednesday got it in 2 days....amazing....and to top it off my mandrel bent ss tubing was packaged infinitely better then I would of imagined. The price was amazing. I literally have no complaints. I will definitely order again. I will say that items on their website were not labeled well so I used vibrants website to look up part numbers so I could get the right parts. Search engine wouldn't bring up items via part number. Kinda confusing but for all I got simply awesome.

Great customer service answered my question with confidence and knowledge

Shipping took a little longer than quoted

Great site Fast service and low price.

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

Shipping was prompt. The Du-Ha storage bin was the correct model for my truck, so the description was accurate. The price on Autoplicity was very competitive.

cheapest price anywhere super fast service will deal with again++++++++
