Most apps sell more to the customers you already have. A gift registry works the other way around. Your customer builds a wedding registry, baby registry or a wishlist for any occasion, then shares it with friends and family who arrive at your store knowing what to buy. Most have never shopped with you before. A saved wishlist becomes a registry when the occasion arrives. Purchases are tracked, so two guests never buy the same gift, and your admin shows every registry, order and revenue.
