"That's definitely not fast food that's my textbook" love it! I like the cash/envelope system and would definitely promote self-control. the Mint option is helpful as well if time is an issue. The entering receipts can be timely but by far probably the most accurate and useful. Thanks for the informative post.
Your right about the cash/envelope system really promoting self control! That's probably why people who are trying to get out of debt/really need to curb spending use it so much. Thanks for the very thoughtful comment!
