Abstract: Systems and methods for providing real-time dynamic pricing information for a product based on receipt of a price queries from consumers at point-of-sale. The system receives price queries for a product provided by a consumer at point-of-sale by way of use of a mobile communicating device such as cellphone. The system maintains a database of received price queries. A preset price query threshold value associated with the product is retrieved in response to a received query. A price query count is extracted for the product, the price query count being the number of price queries generated in a predefined sample period. A product price is calculated in real time based on a comparison between the price query count and the threshold values. The consumer may be provided with discounts or coupons based on marketing campaign parameters derived from the price query.
