Abstract: A system for dynamically pricing products available from one or more merchants. The system sends a first price for a product from a processor to a customer device, and receives a report of sale for the product at the first price from a merchant computer. The system then determines a second price for the product based at least on the report of sale for the product at the first price, and sends the second price to the client customer device.

Abstract: A system for dynamically pricing shelved products in a physical store and/or products available for order in a virtual store. The system dynamically sends prices for a product to a price display unit positioned near the product, and receives reports of sale for the product from a checkout station. Based on the data in the reports, and the timing of the reports, the system dynamically determines the price for the product. For products available for order, the system presents the dynamic prices for the product on a terminal, and receives reports of sale from the terminal.
