Consumers have paid down nearly $127.3 billion of credit card debt since the end of 2008.

Bank card delinquencies fell in the first quarter to 3.88% of outstanding receivables on all accounts, down 51 basis points from 4.39% in the fourth quarter, the American Bankers Association said last week. The decline was the first since 2002.
