The money-saving ideas in Amy Dacyczyn's new book run the gamut from extraordinarily simple items contributed by readers of her newsletter to two- or three-page treatises on how to draw up a family budget or persuade children that expensive snack foods are not necessities. Here are a few brief suggestions:
* Patronize auctions of surplus material at your local armed services base. Typical items include furniture, sound equipment, trucks, boats, even items for children. Call the nearest military base and ask for the Defense Reutilization and Marketing Office.
* Punch holes in the bottom of plastic film canisters and use them as salt-and-pepper shakers for lunch boxes.
* Many communities now charge for trash disposal by the bag. To cut down on waste: omit overpackaged convenience foods; buy concentrated products and those sold in recyclable containers; and bring your own bags when you go shopping.
* Shop for picture frames at yard sales. Replace the unwanted art work with your own.
* If you spend $50 a month or more in telephone calls, you may benefit by comparing various long-distance services. The Telecommunications Research and Action Center will send you a chart comparing the plans if you send a business-sized, self-addressed, stamped envelope and $2 to: TRAC, P.O. Box 12038, Washington, D.C. 20005.
* For overnight stays on vacation, if you can't camp or stay with relatives, look into staying in a college dormitory, YMCA, or hostel.
* Instead of buying expensive nuts for baking, try shelled sunflower seeds, available from health-food stores.
