A host may provide a crowd-source price program. Participants in the crowd-source price program are incentivized to participate by rewards offered by the host. A participant acquires commercial information related to goods, services, or both being offered by a merchant and provides the host with the commercial information. The commercial information may include a purchase price for goods, services, or both being offered by the merchant and may include an identifier corresponding to the goods, the services, or both. The host may validate the commercial information, generate a reward, and provide the reward to the participant. The reward may be an offer for goods, services, or both offered by the host. The participant may accept the reward.
