When in doubt, brew up
The markup on a cup of coffee can be up to 300% — sometimes more for premium or “signature” roasts — and some 16 billion coffee cups are disposed of each year. Save your money and save the planet: brew it yourself!
If you absolutely must buy yourself a daily caffeine hit (or a hot chocolate), get a reusable mug. Plus, lots of places will give you a discount if you bring your own cup.
