+1 and I only use cash for them. I have $400 of misc on a monthly basis that I do not keep track of at all. This covers anything not allocated in my budget - stamps, gifts, a cute knick knack from home goods, lunch with coworkers, coffees. Essentially, it is made up of 85% discretionary purchases. Everything else is categorized and charged on our credit card.
