Now through April 29, you can earn Bonus Stars if you are a My Starbucks Rewards member! Just sign in or sign up, and check your inbox for the offer titled “Grab lunch and 3 Bonus Stars” or “two more reasons to enjoy summer”. The offers will be coming from the email address Starbucks@e.starbucks.com.
Offers vary by customer but these are the two I’ve heard about. Plus check your inbox for another offer valid for 25% off tea through April 29. Please note that you must pay with your registered Starbucks card in order to qualify for either of the offers.
