Packed lunches for fun and profit

When I bring lunch from home, it costs an average of $2 for a sandwich (my favorite is peanut butter and jelly), yogurt, and fruit (hey, this lunch-bringing has the side benefit of also being healthy!). Drinks are provided by my employer, so I don't need to worry about that.

So let's see, four days bringing lunch at $2 plus one day out at $7 equals $15 per week. Eating out every day would cost $35 per week, so I save $20. $20 a week! That's over $80 a month -- that covers my utility bills right there. Who couldn't use that?
