Falling unemployment and consumer confidence have led to more traffic for some retailers, but not all. Beleaguered department store chain Bon-Ton Stores Inc. said Monday that revenue at stores opened at least a year fell 2.9 percent for the nine-week period ended Dec. 30. Total sales fell 4.3 percent. The company is negotiating with its debt holders. The ailing Sears Holdings Corp. said last week that it would close more than 100 additional stores early this year.
