With any gift card, you can join Starbucks Rewards for a free coffee beverage on your birthday and other rewards. When you register your gift card number on their site, you can earn a star for every purchase, reload your balance so you can accrue stars, transfer balances between multiple cards and protect your balance if its ever lost or stolen.
This Starbucks Rewards is a replacement for its old Gold Card Rewards, which you had to pay a hefty fee to join. Five stars, or five purchases, earns you two hours of wi-fi, free beverage customizations like syrup and other rewards. Thirty stars earns you a customized card and free beverage. And 10,000 stars earns you your own in-home barista. Just kidding.
