Here's a list of my top money saving tips:
1)Eat to live - don't live to eat
 Small to moderate sized portions of meats, vegetables and fruits will keep most folks out of the doctor's office.
2)Limit severely or completely do away with the tv
Watching tv can fuel your desire for more 'stuff' - use that time for hobbies, reading, relationships etc.
3)Use the 'envelope' method
Label letter size envelopes with your budgeting needs - 1 envelope for groceries, 1 envelope for home needs, 1 envelope for car care etc. Each week, or whenever you get paid, plan out how much money should be divided up into each envelope. When the money is gone out of that envelope, that's all that can be spent in that category until the next payday. It may take a few tries to get the amount just right in each envelope but this has been a great help in keeping us from overspending.
