A+shipping was quick, communications were quick

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

Purchased a roll-n-lock bed cover. Ordering was easy and it was the lowest price by far that I could find online. Shipped within 48 hrs as informed. I have not yet rec'd it so I cannot comment on the packaging just yet. Sofar a good online purchase experience.
