L.L. Bean must make stocking decisions on thousands of items sold through its catalogs. In many cases, orders must be placed with vendors twelve or more weeks before a catalog lands on a customer's doorstep, and commitments cannot be changed thereafter. As a result, L.L. Bean suffers annual losses of over $20 million due to stockouts or liquidations of excess inventory. Provides a context in which buying decisions that balance costs of overstocking and understocking when demand is uncertain are made and implemented on a routine basis.
