Last September, my family and I did the Living Well Spending Zero challenge from Ruth Soukup. As part of the challenge, we spent minimal money for the entire month. No groceries, no entertainment, no take-out. We allowed ourselves a small amount of cash at the start of the month for minor necessities, and activities that had already been planned, but that was it. We ate through the food in our refrigerator and pantry, learned to ration our seltzer, and went to some free events like the Fork Food Lab grand opening.
Overall, we did a great job, or at least until the last day of the month when our cat came down with a UTI, and we had to do an emergency visit to the vet complete with x-rays, anesthesia, and multiple antibiotics, all of which negated most of our savings from our zero spend month. Still it was a fun, creative experiment and one we would definitely try again. More importantly, our cat, other than one minor setback, is doing great now.
