Receipts may be received at a location that a customer normally uses to receive electronic correspondence, such as an e-mail address, an instant messaging address, etc. Among the items that are sent to that location, those items that contain a receipt may be identified. The identified receipts, or information extracted from such receipts, may be sent to a receipt store. An action, such as displaying the receipts to a customer, may be taken based on content stored in the receipt store. The information that is stored in a receipt store and/or that is displayed to customers may have an arbitrary level of detail. |
