Make-A-Wish Idaho announces the return of Macy’s beloved Believe letter-writing campaign which gives believers of all ages the opportunity to send letters and deliver wishes. From Monday, Oct. 26 through Dec. 24, for every letter sent to Santa online at https://mcys.co/32nuL90 or dropped off in Macy’s stores, Macy’s will donate $1 to Make-A-Wish, up to one million dollars, to help children fighting critical illnesses.
