Bank of America Corp plans to charge customers who use their debit cards to make purchases a $5 monthly fee beginning early next year, joining other banks scrambling for new sources of revenue. Senator Richard Durbin, architect of debit card interchange fee reform, bashed the proposed monthly fee. "Bank of America is trying to find new ways to pad their profits by sticking it to its customers," he said in a statement. It's overt, unfair, and I hope their customers have the final say."
