Macy’s beloved Believe letter-writing campaign, in partnership with Make-A-Wish, returns for the 13th year giving believers of all ages the opportunity to send letters to Santa and deliver wishes to children fighting critical illnesses. From Monday, Oct. 26 through Thursday, Dec. 24, for every letter sent to Santa online at macys.com/believe or dropped off in Macy’s stores, Macy’s will donate $1 to Make-A-Wish, up to $1 million, to help children fighting critical illnesses’ life-changing wishes come true.
