If you expect to make multiple content scan and/or mail shred requests, you can save by purchasing bundles of 5, 10, or 20 requests from your Mails forever account.
A request covers 10 pages. If you exceed 10 pages, it will be counted as a second request.
Bundles have no usage time limit, but any unused scan/shreds will be non-refundable if you cancel mailbox service before using them up.
