This is essentially the same promotion as was mentioned earlier for Delta Skymiles card holders, but is instead for solicited Amex Green and Gold Card holders. When you enroll by June 15, 2007, you’ll be eligible for double points spent on your account between April 15 and June 15, 2007:

…you must enroll using your 14-digit RSVP code from your mailing, or if you are registered to manage your account online, your user ID and password.

To enroll in this special offer you can also call 1-800-794-1308 and enter the nine-digit code 064570002.
