must be solicited. No go.

I have 7 AMEX cards, only one eligible was my Blue.

On all three of my amexes:
We're sorry. This special promotion is only open to solicited Cardmembers

I got a platinum and it worked on mine.

enrolled my blue card, thats the one i got the offer for.

upon enrollment i got this msg.

Please note that by enrolling the Card below, all eligible purchases made on consumer or small business Card(s) linked to your Membership Rewards® account contribute toward the monthly spend threshold specified in the offer you received by mail or e-mail..

you get double points on all linked accounts as well.

We're sorry.

We're sorry. This special promotion is only open to solicited Cardmembers.

If you are a solicited Cardmember and are responding to the offer you received by mail or e-mail, please verify your 14-digit RSVP code located in step 1 of the offer, or if you are registered to manage your account online, enter your user ID and password.

FYI, There is another link to sign up for the double points.

I received an email from AMEX on my Blue for Students with the link to http://www.AmericanExpress.com/doublepoints333. OP's link goes to http://www.AmericanExpress.com/doublepoints484.

Interestingly enough, when I tried to signup at the link OP provided, I received the same rejection notice others are getting about the promotion only being for selected card members. When I went to the link provided in the email from AMEX, it allowed me to signup no problem.

Hee's that other link if anyone wants to try again: Alternate Link for doublepoints promotion

Also, note that the terms and conditions change depending on which link you go through. For the 333 link, here's what the website says: "Enroll now to earn double Membership Rewards® points from June 1 through August 31, 2007. Then indulge yourself in sensational rewards even faster.

You can earn double points on virtually everything you charge from June through August. For example, if you charge $250 one month, you can earn 500 Membership Rewards points. Simply enroll by July 15, 2007.

Please see important terms, conditions, and restrictions below."

For the 484 link OP had, the part in bold above changes to say "Each month, as usual, you can earn 1 Membership Rewards point for virtually every dollar you spend. Then, you can earn 1 additional point for virtually every dollar you spend over the threshold specified in the offer you received by mail or e-mail."

So it looks like the 333 link is a better deal if you can get it. YMMV as always though.

No go for both links. Thanks. Maybe someone will find a third link that may work.

AMEX Delta & corporate not eligible not that I thought it would be
