A system and a method are disclosed for aggregating demand for a merchant using short message service (SMS). The system receives a text message from a consumer containing a merchant code and a request for a discount, the merchant code being associated with a merchant. The system determines whether the merchant has an available discount. If a discount is available, information about the discount is sent to the consumer. If a discount is not available, a text message is sent to the consumer indicating a level of demand for discounts from the merchant, the text message to be shown to the merchant.
