THE CREDIT CRUNCH DOESN’T SEEM TO HAVE HIT BOTTOM: In the line at Target yesterday, I watched a woman have her credit cards declined. The response: Want to take out a Target Credit Card? On the other hand, her instant application for that was declined, too. She wound up writing a check for several hundred dollars worth of cakes, pies, and cookies. Meanwhile, I keep getting mailers from my credit-card companies inviting me to use the credit line with handy “checks” that produce an instant high-interest loan.
