These aren't specific Disney saving ideas, just great frugal trips -- try reading
The Tightwad Gazette books for great ideas (and some really zealous ones too.) These are often available in libraries.
My husband and I are religious about making and taking lunches to work. That easily saves $20 per person each week.
We also have started making sure that we are never without a little cash so we are not tempted into going to an ATM and having to pay bank fees if it's not our bank - that's $1.50-$2 each time around here.
I also eBay alot of my books. I buy paperbacks from my local library for 50 cents apiece and, once I'm done reading them, I eBay them in lots. If they don't sell, I donate them back to the library.
We are lucky enough to have bought a well-insulated house and spend about a 1/3 what our neighbors spend for electricity/gas. We also got a new furnace (old one died!!) and that has increased the efficiency of the house. To add to the savings, we have a computer-controlled thermostat and have it set to lower the heating temps (during the winter) and raise the A/C temps (in the summer) while we are not at home or asleep. That saved a bundle.
Additionally, I hung a long clothes rod in the laundry room and I air dry all towels, jeans, sweatshirts,and other "heavy" items until almost dry. Then I quick tumble them in the dryer so they're not stiff-as-a-board!!
I think this thread is a great idea for a sticky!!
