Help Make-A-Wish Colorado grant wishes by writing letters to Santa as part of Macy’s Believe! Now thru Dec. 24, Macy’s will donate $1 to Make-A-Wish for each letter received, up to $1 million. Write your letter online or drop it off in-store at a Macy’s red letterbox. When you write letters to Santa, you’ll help spark joy for children with critical illnesses – and create hope for brighter days ahead.
