Collecting method by information processor, and ordering method or sale method

摘要

Collection methods of toner cartridges involve stores or manufactures dispatching recovery vehicles, users taking toner cartridges to stores, or users sending toner cartridges by packing them in special boxes, but all these methods are troublesome and costly. To deal with this situation, an ordering screen provided to the user who orders goods via an Internet contains an entry field for specifying whether to use a collection service for the goods to be ordered. When this field is filled in and the information as to whether to use the collection service is transmitted, a main server calculates expected collection quantities based on the transmitted information and then draws up collection plans based on the calculated information.
