You could save a LOT of money on coffee in January if you’re willing to make an investment up front . . . and do some math to make sure this is a good deal for you.
Right now, you can buy a 16-ounce tumbler at Starbucks. It costs $40. BUT . . . you can get it filled with free hot coffee or hot tea every single day in January.
So if a coffee is around $2.50, you’d need to go to Starbucks 16 times to break even. But if you go all 31 days in January, you’ll come out close to $40 AHEAD. (Delish)
