Michael Petruccelli says:
Pack Your Lunch and Save $1,800. If grownups took a page from their school days
and packed a healthy lunch, and snacks too, they would save $1,800 a year. That’s
because if you buy lunch out every day (cheaply, I might add), you spend more
than $150 each month for that convenience. Sure, it’s nice to have someone else make you lunch, but I like the idea of $1,800 in my bank account at the end of
the year better.
