A method, system and computer program product for increasing the sales of a retailer. A unit, referred to herein as the “retailer promotions device,” generates a group offer for a set of users/customers to purchase a product based on intelligent analytics (e.g., real-time attributes/dynamics such as the strategy in selling the remaining inventory). A group offer refers to an offer to sell a product at a promotional price if a number of users (e.g., users of mobile devices and/or customers online and/or customers in a physical store) agree to purchase the product at the promotional price within a time period. The group offer is sent to targeted users/customers via online and mobile devices as well as via electronic displays and kiosks in the physical store. By using real-time attributes/dynamics to generate group offers that can be sent to targeted users/customers, the sales of the retailer are likely to be increased.
