From the article:
"Marriott is also getting into the flash sale website business with the introduction of FlashPerks. Through FlashPerks, Rewards members can redeem points or use cash for limited-time, exclusive deals.
The FlashPerks will be available in the USA starting July 17 at marriottrewardsflashperks.com. About 10 to 15 flash sales will be announced each week over 12 weeks. Each offer will last for a certain amount of time or until it sells out. An example of a deal would be 50% off executive suites at the JW Marriott Marquis Dubai, the world's tallest hotel, plus 20% off the spa and free access to the lounge."
Cheers.
