Autoplicity must have sent my Airaid CAI within hours of my order because UPS delivered it right away. I even got it before I received an e-mail indicating the order had been processed or a notification of shipping e-mail. <br><br>The online advertised price seems to vary by about $20 and that means that you must monitor the site if you are to get the lower price. However, Autoplicity has arranged with BuySafe to give you the difference if you establish an account with them and go through the process. This process was not easy as there was an apparent database problem where the Autoplicity URL was not taken by BuySafe. A call to BuySafe got that worked out, I am hopeful that I will receive the refund promised via paypal. It looks like a good system if it works.<br><br>The bottom line is that Autoplicity offers the best online price by far and although my unfamiliarity with how they do things caused some confusion on my part, they do have a good order processing and price guarantee in place.

So far, so good. As long as there aren't multiple delays in shipping as I experienced with a competitor, before I found Autoplicity, then this will continue to be a 5 Star. Thanks.

Quick and easy.

Quick and easy. Price was great also

easy transaction

fast and easy competitive pricing

Very good!

Cool site.

As always fast, easy and reliable

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.

Great prices and great service. It was shipped the next day!

Great
