Ready for a month's worth of free coffee???

Well... Sort of free. But here's how you get it!

According to

Available in stores now, the 16-ounce Brewed Refill Tumbler can be purchased at any Starbucks store for $40. Once you've got it, you can return every single day in January for a free Grande brewed hot coffee or hot tea.

I'm pretty confident I could make $40 worth it over the course of a month. Because CAFFEINE!
