A customer uses a mobile device to verbally request an offer that includes an incentive to transact at a merchant's brick and mortar store in the customer's local community in exchange for the merchant's agreement to make an auditable donation to a charity serving the local community. Business rules limit the merchant's charitable donations over calendar periods, which donations can be made directly by the merchant to the community charity, or indirectly to the charity by way of a blind donation made by the merchant to a donation disbursement agency acting on the merchant's behalf to satisfy the merchant's commitment to donate.
