A new Wal-Mart effect?

This item in The New York Times is, well, not unexpected but very odd:

When Best Buy announced its latest sales figures last month, the company reported “an unprecedented drop in consumer buying of items like flat-screen televisions,” said Ori Brafman, a business expert and an author, with his brother, Rom, of “Sway: The Irresistible Pull of Irrational Behavior,” out since June from Doubleday Business. “But when Wal-Mart released its report last week, there was a surprise. Consumers had increased their flat-screen purchases. Somehow, because Wal-Mart feels like a bargain store, shoppers who have deprived themselves of luxury items elsewhere rationalized their purchases at Wal-Mart as ‘getting a good deal,’ ” Mr. Brafman continued. “Granted, flat-panel TV’s at Wal-Mart might run a little cheaper than elsewhere, but no financial adviser would include one on his or her list of Items to Buy During Tough Times.”
