In order to archive a promotion, log into your account and navigate to Products > Settings> Promotions.  The screen will contain two sections, one for active promotions and one for archived promotions. Find the promotion you wish to archive in the table and select Archive from the Actions menu.

Archiving a promotion prevents it from being used by a customer during purchase.

After you select Archive the promotion will be removed from the active section and placed within the archived section of the page.

If you need an archived promotion in the future you can easily reactivate it by finding the archived promotion in the archived section of the page and clicking Restore. The promotion will be added back into the active section and available for use by customers during purchase. It is important to note that active promotions that have expired will still not be valid for use.
