By gross, I don't mean the roadkill idea from the previous post ;)
Question is: Will tallying $$$ spent be based on net or gross? So if I get 10 cans of soup for $1, will I tally the $.10 once I consume it or do I count the whole dollar? What if I want to eat 5 cans pre-challenge and only use 5 during the challenge, would I just count $.50?
Also, we need to rule if gas/mileage is exempt (pre-challenge and during challenge).
