Abstract: 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.

Abstract: Techniques for managing a return request may be provided. For example, a user may want to return an item that the user received from an item provider via an electronic marketplace. The user can take a picture of the item and transmit the image to a computer that determines that the user would like to return the item. The computer may also determine that the item is returnable (e.g., was provided to the user within an allowable timeframe, satisfies a constraint for returning the item). The computer can initiate a return of the item. In some examples, the computer can also determine a convenient return location or the reason that the user is returning the item to the item provider.
