One of my best investments was a reusable coffee cup. Before, I spent $5 or more a day on coffee to-go, racking up around $1,500 a year in disposable cups and lids. After switching to a reusable cup, I cut that down to almost nothing. Not only does it save me $200+ a year, but I’m also reducing waste and supporting coffee shops that offer discounts for bringing my own. It’s a small change, but the savings really add up over time. If you’re looking for an easy and effective way to save money while being more eco-conscious, start with a reusable coffee cup.
