Reuse. Products that can be reused are cheaper in the long run than those you throw away and buy over and over again. Goods that are designed to last a long time are also cheaper in the long run than those that wear out quickly. A family can save $1,000 each year by buying reusable and long-lasting products. For example, use rechargeable batteries in toys, flashlights, radios. You can save $200 a year by using rechargeable batteries instead of disposables in one CD player used two hours a day. Not only does it save you money, but it saves on the energy used to produce the products and it means less waste getting thrown away.
