Frugality is making a comeback.

Fearful that economic conditions could get worse and stay that way, Americans are showing an enthusiasm for thriftiness not seen in decades.

This behavioral shift isn't simply about spending less. The New Frugality emphasizes stretching every dollar. It means bypassing the fashion mall for the discount chain store, buying secondhand clothes and furniture, or trading down to store brands.

There's more business for repairmen and less for salesmen. Consumers are clipping more coupons and swiping their credit cards less.

The trend is evident in where cash registers are ringing, and where they are not.

Wal-Mart, BJ's Wholesale Club and Goodwill thrift shops are thriving, while Saks and Abercrombie & Fitch are struggling. Likewise, as casual dining chains such as O'Charley's and Red Lobster see fewer customers, McDonald's is serving more, including people who have given up $4 Starbucks drinks in favor of the fast-food chain's expanding coffee menu. Even Spam has made a comeback.

Tellingly, Wal-Mart said recently it has seen a 2 percent jump this year in shoppers from households earning at least $65,000.

Retail sales fell 2.8 percent in October, the fourth straight monthly drop, as unemployment hit a 14-year high of 6.5 percent.

The National Association for Business Economics on Monday projected that the overall U.S. economy, after shrinking at the annual rate of 0.3 percent in the July-September period, will contract at a rate of 2.6 percent in the current October-December quarter.

The housing bust, credit crunch and stock market plunge have eaten away at the retirement savings and confidence of consumers who for years operated on a buy-now, pay-later ethos, chasing bigger homes, bigger cars and better brands. That is forcing families to bring their spending in line with their income and to rethink priorities.
