Normal dates—with the requisite mani-pedis, barbershop shaves, drinks, and movie tickets—can easily add up to more than $200. But just because you’re single and can’t afford big nights out doesn’t mean you need to forgo sex altogether. Just sleep with your ex. Booty-calling an ex, at least one you’re on good terms with, is a low-risk, high-yield investment. You’re familiar with each other’s flaws already, so no need to mask them with pricey beautification or elaborate mating rituals. Just order in Chinese—or better yet, nuke some Ramen, then get busy. Bonus perk: Your ex knows his or her way around your body, and vice versa, which means a guaranteed good time for all.
Annual Savings: $2,400
(Compared with twelve $200 dates.)
