This offer came with my American Express Business Platinum card.
Through 1/15/2018, you can get 2,000 additional Membership Rewards points one time after you use your eligible, enrolled Business Card from American Express OPEN to spend a minimum of $100 in one or more eligible transactions online at Staples.com.
I enrolled and although I had nothing to spend $100 on at Staples, I purchased a supermarket gift card. I know I will definitely use that and I wanted the easy 2,000 points!
If you have an American Express business Platinum card, you may have this offer available to you as well. Login into your account and check the offers at the bottom of the page and make sure you sign up for the offer thru your Amex online account before you shop.
