AMEX Business Platinum is currently offering a bonus for adding employee cards: add one card and spend $4,000 on that employee card within six months to earn 20,000 MR. You can add up to five employee cards, which means you can earn up to 100,000 points total.
Be sure the required spending is completed on the employee card itself. If you do not need the employee card benefits, you can simply choose the no-annual-fee Business Green employee card.
