I’m a big fan of the Financial Feminist podcast. A few weeks ago the host, Tori Dunlap, shared a money hack that she had heard about from another financial educator on Science Finance: Before making an impulse purchase, ask yourself: “How many ‘taco dollars’ does it cost?” That particular financial educator really loved tacos, so he judged each purchase by asking, “How many tacos could I buy for the cost of that item?” Concert tickets: 20 tacos. Cupcake: 1 taco. Fancy hotel stay: 83 tacos. Then, he would ask himself: “Is it really worth that many tacos?”
