 OpenBSD is freely available in various ways: the source can be retrieved by anonymous CVS, and binary releases and development snapshots can be downloaded by FTP, HTTP, and rsync. Prepackaged CD-ROM sets can be ordered online for a small fee, complete with an assortment of stickers and a copy of the release's theme song. These, with their artwork and other bonuses, are one of the project's few sources of income, funding hardware, Internet service, and other expenses.
