Starbucks sent out an email today detailing a new promotion they are running for those who have a Rewards Card–a free drink of your choice from Starbucks on your birthday.
To sign up to receive a free drink on your birthday, you just need to have a Rewards Card (i.e. a Starbucks gift card) and you just need to go here and add your mailing address and date of birth to your Rewards Card member profile and opt in to receive mail from Starbucks.
If you don't have a Starbucks gift card, you can get a $10 card from Swagbucks for 135 points.
Thanks, My Frugal Adventures!
