Starbucks is offering a free $5 gift card for new members of their Starbucks Rewards program that register a Starbucks (gift) card. If you don’t have one, you can either buy one from a physical store or use their mobile app. Ends 3/15/13.
Indeed, the easiest way to get a free $5 gift card is to download their smartphone app (Android/iOS) and sign up for a new account via the app. When asked to register a card, choose to “Get a Mobile Starbucks Card”. You may need to wait a few minutes, but the card should eventually get credited with $5 without having to load it with your own money. Free caffeine, good for at least two iced coffees with milk per person! 🙂
