Join the ‘My Starbucks Rewards’ program to snag a FREE $5 Starbucks gift card! To join, simply register your existing Starbucks card. If you do not have a Starbucks card, you can get one at your local Starbucks (must load at least $5 to it). Once you’ve signed up, the $5 will be added to your registered Starbucks Card within 24 hours. Keep in mind that this is valid for new members only, through March 14th!
