The products will be held in a secured box which will open once the passenger pays through the app. According to a report in CNBC , drinks giant Coca-Cola have partnered, offering it's Smartwater free to riders. Drivers will earn a small percentage and commission from each sale which Cargo claims can increase their monthly earnings by up to $500 (£352).
