America Ferrera ("Ugly Betty") and Ben Feldman ("Mad Men," "A to Z") star on the hilarious workplace comedy "Superstore," about a unique family of employees at a supersized megastore. "Superstore" centers around Amy (Ferrera), the store's most stalwart employee as well as the glue holding the place together, and Jonah (Feldman), a dreamer determined to prove work doesn't have to be boring.
