Priceline.com has pioneered a unique new type of e-commerce known as a "demand collection system" that enables consumers to use the Internet to save money on a wide range of products and services while enabling sellers to generate incremental revenue. Using a simple and compelling consumer proposition--"Name Your Own Price," we collect consumer demand (in the form of individual customer offers guaranteed by a credit card) for a particular product or service at a price set by the customer and communicate that demand directly to participating sellers or to their private databases. Consumers agree to hold their offers open for a specified period of time to enable priceline.com to fulfill their offers from inventory provided by participating sellers. Once fulfilled, offers cannot be canceled. By requiring consumers to be flexible with respect to brands, sellers and/or product features, we enable sellers to generate incremental revenue without disrupting their existing distribution channels or retail pricing structures.
