If you have Starbucks coffee at home, check the bag. I have a Vanilla Infused bag that has small print on one side that says if I bring in the empty bag I will get a free Tall (aka Starter Size lol) brewed drink at Starbucks. Sweet! Even better is that I got the bag at Amazon for under $4...and I have three more in the cabinet. I love a deal within a deal all wrapped up with yummy coffee.
While we're talking about Starbucks, did you know there's a Short size? Yes, it's smaller than a Tall. It's not on the menu and I don't know if all locations/baristas will give it to you, but you can ask. It's a great option to try a new brew or get a smaller drink for kids.
