Marriott Rewards launched More on back in October 2017 (read more here) that allowed members to earn and redeem points for purchases made with select online merchants.
A LoyaltyLobby reader alerted us that this service is coming to an end on November 15, 2018. It is unclear why Marriott Rewards has decided to end their online shopping mall (basically what this is).

Marriott Rewards made some noise about this service when it was first launched about a year ago but I guess that all their energy was used to program integration.
The uptake among membership cannot have been great due to basically non-communication about this initiative in 2018.
