If you’re a rewards member at Starbucks, you’ve probably already seen those personalized gold cards and picked up a free drink on your birthday. But apparently there’s another thing the coffee giant does that no one knows about (or is it just us?): Free refills. That’s right, Starbucks offers on-the-house second servings of brewed and iced coffee and tea to rewards members so long as they stay in the store. All you have to do is purchase the drink with your registered rewards card and literally not leave the premises. After all, when you can get a free drink at Starbucks, why would you even want to go anywhere else? Trust us, your wallet will thank you.
