I agree with some previous posters that sometimes you just can't make a budget work by shaving off a couple of dollars here and there, but still, here are some things we do to stretch our budget:
*Shop around for your auto & home insurance. Sometimes you can find a better deal by making some phone calls, especially if you have both with one carrier.
*Learn to shop grocery sales, stock up on nonperishables when they are at their cheapest.
*Plan all meals in advance, before you do your shopping. You can figure it out so that you have little to no wasted food.
*Replace household paper goods with cloth. No need to buy paper napkins, paper towels, etc. Some folks even use cloth toilet paper, although I have not really won my family over on that one
*Line dry your laundry whenever you can.
*Energy saving light bulbs.
*Turn down the thermostat in winter, turn it up in summer. Stretch your comfort zone.
*Don't buy cleaning products. You can clean almost anything with some combination of vinegar, baking soda, cheap-o dish soap, maybe a little tea tree oil.
*Get the word out that you like hand-me-downs. Watch Freecycle for them too. Sort and store them by size until your kids grow into them. If you don't get enough hand-me-downs, watch clearance sales and thrift stores with an eye to at least one year ahead. I just bought brand new snow boots at Goodwill, in next year's sizes for both my kids, for $2 a pair.
*Take advantage of your local library for entertainment.
*Learn to cut your whole family's hair.
*Since you have a little bit of land, you might consider keeping some chickens for eggs.
