>However, if your company has blocked the American Express Membership Rewards program, you will NOT be able to enroll your corporate cards.
Also
>To earn American Express Membership Rewards points, you have to pay $90 to enroll your American Express Green Corporate card or American Express Gold Corporate card.
So only worth it for people who know they will be big spenders and who won't leave the company for a long time. For someone who travels only once a year (like me) totally not worth it. I'd rather collect the ~$30 cash back on my 2.5% cash back card.
