Over at the frugality centred blog Wise Bread, they crunched the numbers on the caffeine content to cost ratio of 22 common caffeine sources. The king of the caffeine castle isn't actually a drink. No Doze pills have a caffeine content that breaks down to a mere 0.0008 US cents per mg. Uncomfortable outright acknowledging the necessity of your caffeine habit by turning it into a pill-popping habit? Fair enough, you'll want to start drinking the runner up: Tetley's Black Tea.
2. Tetley's Black Tea This British favourite is priced so low, they have it twice a day. What made Churchill so staunchly great? It's the tea, dear. At less than a dime a tea bag, it brings the caffeine cost at 0.0011 cents per milligram. That's so low, it's practically free. God save the queen...and your cash.
One thing worth noting when reviewing the list is that they looked at commercial prices and used Starbuck's as their baseline for buying coffee. The bucket of swamp water coffee slowly reducing itself to char and caffeine powder in the office break room is much cheaper and possibly free.
