These little packets are life savers! I’m on the go a lot, and these are a must for the traveling life. I have bought them at Starbucks, online, and at grocery stores. As I have come to expect from Starbucks, these little packets have a lot of strength to them. When I need a quick energy boost, I use the whole tube in my travel mug. For those days I want a little less strength to my coffee (or when I want to make the precious packets stretch out just a little), I use half and it’s just right. Whenever I see a deal on these, I stock up to make sure I always have a few on hand!
