Abstract: A method of linking a plurality of third-party discounters to a unique customer ID in a retail sales transaction that comprises assigning a unique customer ID to a customer, creating a customer account record that is associated with the unique customer ID, and adding a plurality of registered third-party discounters to the customer account record. The method also includes processing a sale of a good in a sales transaction, identifying a registered third-party discounter associated with the good, and verifying that the customer is currently registered with the registered third-party discounter associated with the good to ensure a current eligibility of the customer. The method further includes applying a predetermined third-party discount to a gross sales price of the good to determine a net sales price for the good, and collecting a monetary value from the customer equaling the net sales price for the good.

Abstract: A system for supplying duplex pharmacy labels comprises a sheet, a printer arranged to print on both sides of the sheet, a database, and a controller. The sheet includes an obverse face and a reverse face, the obverse face of the sheet including a first area and a second area, the first area of the obverse face including a pair of peel-off labels removably disposed on a backing surface. The reverse face of the sheet includes a first area opposite the first area of the first side, with at least a portion of the first area of the reverse face formed by a reverse face of the backing surface. The controller forwards patient-specific data for a selected patient and medication-specific data for a selected medication to the printer, thereby causing the printer to print on the obverse face and the reverse face.
