Great Price, Not too much more for 2 day shipping either.

After searching for the best prices for the product that I wanted, I ended up with Autoplicity. I quickly got a response that my product has just been shipped and I am very impressed that Autoplicity is giving me an incentive to write a review on them. This tells me that this company is very concerned with the satisfaction of their customers. I am currently waiting for the order to arrive, but so far, I am extremely confident and happy with Autoplicity!

Customer Care took care of my return and refunded the shipping after there was some order confusion. Thank you for taking care of everything!

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.
