The recession has clobbered many clothing retailers, but Aeropostale (ARO) has continued to deliver strong results thanks to its value-oriented approach. The New York City-based chain sells teen apparel that's trendy but priced below the duds peddled by rivals such as American Eagle (AEO) and Abercrombie & Fitch (ANF). It serves up a steady stream of promotions and discounts, such as a deal last week that offered two graphic T-shirts for $18.
