An initiator computing device may acquire a digital coupon having a first value. The initiator computing device may share the digital coupon with a recipient computing device. An advertisement server may be notified that the initiator computing device has shared or has an intent to share the digital coupon with the recipient computing device. The advertisement server may calculate a second value associated with the digital coupon and assign the second value to the digital coupon responsive to the initiator computing device sharing the digital coupon with the recipient computing device. Further, the advertisement server may receive logging information associated with sharing the digital coupon. The logging information can facilitate monitoring the influence of the digital coupon.
