fast shipping just what i ordered

Fast checkout

Thanks for ease of purchase.

I've looked for 2 days and could Not find a better price along with the shipping price and guarantee can't beat it thanks

So far so good. Easy ordering

it's so easy I am in the for first time using to buy online because I know speak and read good English but it's so easy to buy it thank you have a great day

Great prices with products and shipping

Great prices for the parts I needed to replace on my SUV, a bit hard to reach customer service when I had a question about the order. When I finally did reach CS, question was answered without any issues, shipping costs seem a bit high.

Was going to also order TCI-618008 with this purchase but the free shipping didn't apply? Just thought you could add it to the same free shipping box.

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.

Excellent transaction, received item very quickly and it was a lot cheaper than any other online retailer that I was able to find, could not even find cheaper on e bay.
