POCATELLO â This year, learners attending Tyhee Elementary School wrote letters to Santa to help Make-A-Wish Idaho grant wishes as part of Macyâs beloved Believe letter-writing campaign. From Oct. 26 to Dec. 24, Macyâs is donating $1 to Make-A-Wish for each letter received, up to one million dollars, to help children fighting critical illnesses. This year, the campaign introduced the National Believe Week in December, doubling donations to $2 per letter, up to an additional 1 million dollars. Make-a-Wish Idahoâs Believe campaign is based on the New York Sunâs famous âYes, Virginia, there is a Santa Clausâ editorial. Now in its 13th annual year, Macyâs invites believers of all ages to write letters to Santa and drop them off at Macyâs in special red letterboxes, use the virtual letter-writing option, or mail them to Make-a-Wish Idaho.
