Starbucks Rewards Members get FREE unlimited refills of hot or ice brewed coffee and tea with any drinks purchase. Just use the card linked to your rewards account to make the purchase. You must enjoy your free refills during the same visit in which you make your purchase which means you cannot purchase your drink to go, leave and then come back for the refill. Just head to your local Starbucks and order any beverage to enjoy in-store. Once you are done, take your empty cup to the register and order any coffee or tea of the same size as the beverage you purchased. Scan your rewards card and enjoy the free and unlimited refill! Once you leave the store, your visit has ended and any subsequent coffee or tea refill thereafter would be considered a new purchase. Refills are not available in the Drive Thru.
