Fast food chain Subway has launched a lifetime supply offer of free Subway Deli Heroes, but only for those who change their first name legally to Subway. The contest runs from 1-4 August. Subway will pay for the legal fees associated with the name-changing process. This is not the first time the company has launched a creative contest - it previously offered a year's worth of free sandwiches for customers willing to get a Subway-themed tattoo. The latest offer is expected to create a buzz and connect Subway with its customers on a personal level.
