Holiday season is almost here, and Macy’s is launching a star-studded ad campaign appropriately titled Believe. Design stars like Jessica Simpson, Martha Stewart, Carlos Santana, Donald Trump, Tommy Hilfiger and Kenneth Cole will appear in the TV commercials launching on Sunday. And they aren’t the only famous faces in Macy’s this holiday season. Macy’s will be setting up Believe Stations in every store that feature a Believe Meter, letter-writing station and an official R.H. Macy Santa Mail letterbox. Beginning on November 9, children across the country are invited to drop off their letters – stamped and addressed to Santa At The North Pole — at any Macy’s store in the Santa Mail letterbox. For each letter received, Macy’s will donate $1 to the Make-a-Wish Foundation and up to $1 million to grant the wishes of children with life-threatening medical conditions. We can’t wait to see the rest of the ads (and to start our holiday shopping!). Tell us: What do you think of Jessica’s Macy’s ad?
