Companies like to offer coupons to entice customers to try products and brands they otherwise wouldn't. However, as a savvy shopper, you can take advantage of this service by looking for coupons on things you already need and buy regularly.
Another trick is to combine deals if possible. For instance, save coupons for things you think you might need soon, and then keep your eye out for sales on that product. Or you could get discounted gift cards and make your purchases during a seasonal clearance [source: Pate]. The savings can be particularly significant.
The keys to coupon saving are flexibility and organization. You need to be flexible about the products you'll get, and not loyal to a particular variety or brand. However, it wouldn't be wise to buy anything you know your family won't use. It'll also help to have a system for organizing the coupons you find. Cut them out of newspapers or print them off the Internet, and keep them in a special container or pocket book. Some coupon experts recommend categorizing them or sorting them them by expiration date [source: Drenth].
