Great Transaction Thanks

This is my second order. Everything was great the first time. Sure it will be this time as well.

very good price

WENT FAST AND EASY THANK YOU

Found an item that has been unavailable every where I have looked.

The resonator I ordered arrived at my house slightly bent, but I called Autoplicity and they sent a replacement by next-day-air, so I was happy about that. It's a little hard to reach people there when you need to get a problem resolved, but in the end it all worked out.

Good service and quick response. The prices were the best around and the business was completed quickly.

Quick and easy.

Easy fast and good price

Lowest price available online

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.
