I also don't count bills.
I count the money I give DH as a bill, and therefore not a spend day. I could never keep up with his spending. He usually gets a 50 cent soda for lunch every day at work, but some days that is all he has for lunch. He works hard and spends less than $80 a month on all his stuff. If he is willing to work, and needs a candy bar, go get it (he works in a grocery store, so usually picks something up every day and brings part of it home to finish as a snack).
I also don't count gas.
I count groceries, drug store, convenience store pick ups, newspapers, fund raisers, church events other than regular tithes and offerings (money to buy children's church bells, etc)
