Fans of Carvel ice cream located in New York City will be able to get a free treat from a very special source on Wednesday, June 18. The soft serve ice cream chain, a subsidiary of GoTo Foods, will serve its product directly from what it is calling a first-of-its kind interactive billboard on Perry Street in New York City’s West Village on June 18 from noon to 7 p.m. EDT. All consumers can receive a free vanilla soft serve while supplies last. Members of the Carvel Fudgie Fanatics loyalty program will also receive free sprinkles on their ice cream. The retailer will also give the first 50 loyalty members who show up exclusive gifts like t-shirts and Carvel gift cards. Consumers can sign up to be a member of Fudgie Fanatics before June 18 for free on the Carvel site or on the spot at the billboard. All attendees will have the chance to participate in special giveaways and surprises throughout the day. All Carvel locations nationwide will offer a “buy one get one free” sundae or ice cream on Wednesdays throughout the summer, starting June 18. A dispenser billboard typically refers to a billboard or advertising display that incorporates a physical dispenser mechanism, allowing it to dispense samples, coupons, brochures, or small products to passersby.
