Abstract: Electronic sales promotion information is created that includes multiple sales promotion items that may apply to the same product sales transaction, and electronic sales orders are processed using the created electronic sales promotion information. A method of creating sales promotion information includes receiving user-initiated input to generate a sales promotion marketing item and associate the generated marketing item with sales of a selected product. If one or more sales promotion marketing items have been previously associated with sales of the selected product, a user is provided a display of the previously associated marketing items to guide user design of conditions among the newly associated marketing item and the one or more previously associated marketing items. User-designed condition information is received and electronically stored for use in a subsequent computer-executed process.
