Like coffee? Don’t like spending exactly $1,539 a day on a single cup of the good stuff? Then brew your own!
Step 1: buy coffee and keep it in your desk.
Added bonus? It'll act like a coffee air freshener for your cubicle
Step 2: buy a single cup coffee filter cone and some tiny little coffee filters***.
Best $3 I've ever spent.
Step 3: Profit! Oh, wait. This isn’t the Digg.com comments section.
Step 4: Place your Step 2 over a mug of your choice
Step 5: Put two big scoops of your Step 1 into your Step 2. Add really really hot water.
Step 6: enjoy.
***If you’re really cheap (or really broke): use a pen to poke a hole in the bottom of a styrofoam cup instead of buying the shiny Melitta thing, and substitute a folded-up paper towel for the coffee filters.
I make my own damn coffee at home with a french press. Not quite as cost effective as what you are talking about, but this Frieling tank is awesome!
