NEW YORK - Quite a number of people who rushed to snag holiday discounts on TVs, toys and other gifts are quickly returning them for much-needed cash. The shopping season started out strong for stores, but it looks like the spending binge has given way to a holiday hangover.

Return rates spiked when the Great Recession struck and have stayed high. For every dollar stores take in this holiday season, they'll have to give back 9.9 cents in returns, up from 9.8 last year. In better economic times, it's about 7 cents.

Those fractions of a penny add up. Stores are expected to take in $453 billion during this year's winter holidays. Merchants make up to 40 percent of their yearly sales in the last two months.

Returns are typically more associated with January than December. After all, that hot pink sweater with yellow stars on the sleeves may not be exactly what your sister had in mind. But these days, more is going back before it ever gets to Santa's sack.

"When the bills come in and the money isn't there, you have to return," says Jennifer Kersten, 33, of Miami. She spent $300 the day after Thanksgiving on books, movies and clothes for her nephews. She returned half of it.

Some reasons for the many unhappy returns:

Shoppers are bingeing on big discounts. Stores are desperate to get people in the door. But the same shoppers who find a "60 percent off" tag too good to resist may realize at home that they busted the budget.

Stores have made it easier to take things back. Nordstrom is letting online shoppers return items at no extra charge this year. It used to charge $6. Other stores are offering more time to return or rolling out "no questions asked" policies - no tag or receipt required. But that can backfire.

Stores are undercutting each other in a tough economy. Wanda Vazquez spent $39.99 at a New York Target on iPad speakers for her 12-year-old daughter, then returned them when she found something similar for $16.99 at Marshalls.

Consumer electronics in particular are being returned at a rapid clip. Stores and manufacturers are expected to spend $17 billion reboxing, repairing, restocking and reselling electronics this year, up 21 percent from four years ago.

At half of the 100 electronics manufacturers and stores surveyed by Accenture, a consulting firm, return rates have increased over the past three to five years. Most of the items are returned without flaws.

In an industry where profit margins are thin and competition is brutal, those return rates are unsustainable, says Mitch Cline, managing director of Accenture's electronics and high-tech group.
