If you run out of candy on Halloween night, no need to worry. M&M's has you covered.
The first-ever M&M's Halloween Rescue Squad will be available to send emergency candy to you and it's free.
The Rescue Squad team will work via GoPuff and deliver to participating locations of that service. All you have to do is
visit M&M’s Halloween Rescue Squad site and request more candy to be delivered to you.
M&M's will take it from there and deliver the candy free of charge within the hour of your request while supplies last.
