The world is your coffee cup. Fill it up with free coffee! Or, any coffee shop drink of your choice if you’re headed to Peet’s coffee. To those of you who are not Peetnik reward members, you can sign up and get a free beverage of your choice upon your first check-in to your local Peet’s coffee shop. The easiest way to do this is by downloading their app, though you can also simply create an online account and check-in through that.
