I obtained the $750 certificate from C/D. Here's how:
(1) You must disable your "Adblock Plus" or other similar "pop-up/spam protection software. I use Mozilla Firefox for my isp, and I clicked on an "ABP" red octangular icon on my toolbar. I selected from the drop down choices, "Disable on www.CafeMom.com". This allowed pop-up ads to appear. I believe the ads are random, and finally a minivan slowly appeared in a pop-up on one of the "Group" sites.
(2)Upon clicking on, a registration screen appeared. After completing, a message informed me that a certif # for the rebate would be emailed to me.
(3) Soon, an email from C/D arrived with a certif # to be printed, and presented to your C/D dealer for $750 towards a 2008 C/D van.
(4)Retail delivery must occur between June 1-July 31 and this can be combined with other incentive offers.
(5) Don't forget to re-apply your pop-up blocker protection if desired.
