What an interesting idea.:
For the month of November, I’m only spending $30 on food. The only exception will be things that are freely available to the average person (salt taken from restaurants, sauce packets from Taco Bell, free coffee from an office). Buying in advance is fine, but at the end of the month, it all has to add up to $30 or less.
My favorite part is that he took the time to write it up and share what he found.
