Editing Cancelled-to-order (section)

==Background==
While some collectors value mint postage stamps, others prefer to collect stamps that have been used. In practice, it is slow and difficult to build a comprehensive collection by removing stamps from mailed envelopes, so modern postal administrations accommodate collectors by offering new stamps already cancelled. The advantage for collectors is that the stamps count as officially used without being subjected to the stress of actually going through the mail. Also, the postal service can arrange a relatively light and unobtrusive cancellation mark.
