Apparatus and methods for a stacking purge-bin (“SPB”) are provided. The SPB may be configured to rotate. The SPB may include a plurality of receiving sections. One or more tangible items retracted by the SSK may be stored in each receiving section. Rotating the SPB between each retraction may prevent tangible items from two consecutive retractions from being stored in a single receiving section. Preventing tangible items from two consecutive retractions from being stored in a single receiving section may allow each tangible item to be associated with transaction information corresponding to a retraction. The SPB may store separators. A separator may be inserted between tangible items received from two consecutive retractions. Separating between tangible items received from two consecutive retractions may allow each tangible item to be associated with transaction information corresponding to a retraction. Transaction information associated with a retraction may be marked on the separator.
