PALO ALTO, Calif., Dec. 12, 2013 /PRNewswire/ -- Deliv, the same-day delivery company, today announced alliances with three of America's largest mall operators, Simon Property Group, Macerich, and Westfield, to provide the convenience of same-day service to shoppers in malls across the U.S. starting this holiday season. This follows a similar same-day delivery partnership announcement from General Growth Properties (GGP). Collectively, the four mall operators manage over 660 malls including thousands of retailers across the country. Each of the mall owners are leveraging Deliv's solution and building out the critical layer of infrastructure including providing runners, concierge services, safe item storage, shipping consolidation locations and dedicated parking for crowdsourced delivery vehicles. Deliv's breakthrough model for same-day delivery uses crowdsourced delivery personnel and an intelligent technology platform to provide premium quality, same-day delivery at affordable prices. Managing a community of these on-demand drivers across the country, the Deliv platform incorporates smart routing and full transparency, including the ability for shoppers to watch their delivery on a map real time from pickup to their doorstep. Shoppers are becoming more tech-savvy and reliant on technology to provide on-demand services to enhance their shopping experience. This infrastructure enables all retailers in a mall to offer cost effective and flexible same-day delivery to their shoppers, making use of the scale provided by multiple tenants working together in a single delivery system. For example, a dad and his kids have a holiday shopping list including clothes, luggage, sports equipment and something for the family dog. He purchases items from several Deliv-enabled retailers including Chicos, Naartije Kids, Tumi, Sport Chalet and Pet Food Express. Rather than carry all his bags with him from each store, he leaves his bags with the store associates where he requests the items be delivered to his house two hours later.
