Easy to place order using amazon

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.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

I think I had to remind them to ship my item but once I did it shipped the next day. The package had the wrong label on it so I wondered if I got the right item but I did and all is well.

My first order from autoplicity. Good products and good prices. Received an order confirmation right away and a shipping confirmation within 1 business day. Have not received my order yet but if all goes as expected I shall be a return customer.
