A buying group discount system includes a universal discount card to provide discounts, rewards and/or offers to consumers participating in a buying group. Consumer purchases are aggregated with transactions of the entire buying group. Rewards and discounts are released to the buying group when the aggregated purchases satisfied criteria specified in a reward policy established by sellers. Furthermore, mechanisms are provided to enable the universal discount card to be positioned to provide contextual flash offers or advertisements.
