Does your Starbucks Rewards card have to have a balance in order to earn stars?!
~Thanks for answering (:
I am an employee, and yes you do in fact need a balance to earn stars. You can load your card first and then use it to pay for your drink. You will also receive free syrups and milk substitutions as well. If you have any concerns that it is not working properly there is a 1-800 number on the back of your card and they can answer any questions you have.
I think as long as you scan the card you get stars. It still counts the amount of drinks you are buying.
