Stung by rising gasoline and food prices, Americans are finding creative ways to cut costs on routine items like groceries and clothing, forcing retailers, restaurants and manufacturers to decode the tastes of a suddenly thrifty public.

In New Hampshire, George Goulet is no longer booking hotel rooms at the Hilton, favoring the lower-cost Hampton Inn. And in Michigan, Jennifer Olden is buying Gain laundry detergent instead of the full-price Tide.
