In a comment on content (and I think that it was THIS channel), the poster called paying for subscriptions that you don't use a "complacency tax." Brilliant!
I do not consider eating out to be a food cost. People have probably only four Needs: Shelter, Transportation, Food, and Medical/Dental expense. (Need = Expense so that you can live, work, and be healthy.) Nicole is correct to focus on the costs of Shelter, Transportation and Food, as these are one's greatest expenses. Eating Out is a Want, not a Need. You won't find me saying never to buy a Want, but Nicole is correct that Eating Out is an expense to be kept low. To lower your Food expense, don't waste food. Somewhere around at least one-third of our food goes to waste. (Food waste is bad for the environment, too.) Tighten up on your meal planning a little to reduce food waste, and your Food expense will automatically be reduced. (What -- did you think I was going to suggest that you to eat less?)
