Every year during the yearend holiday period Marriott has been running promotions for buying Marriott branded gift cards. Normally you have few choices like extra Marriott points for purchases, 10% discounts of the face value, or 10% more on the gift card that you can buy at original face value. This year is no different.
All these Marriott gift card purchases earn 5 Marriott Rewards points per dollar charged when paid using Marriott Rewards Visa credit card. Also, you can earn cash back for purchasing these through online cash back websites. Currently Ebates is offering 1%, Fatwallet 2.5%, and BigCrumbs 4% for buying these by first linking to Marriott through their websites. Please refer each of the respective websites for more information about the cash back rates that may change.
