Originally the newsgroup "misc.forsale", the Usenet
    Marketplace is now a collection of 38 worldwide newsgroups
    under the misc.forsale and biz.marketplace hierarchies.
    These groups provide a forum for individuals and companies to
    offer goods and services of widespread interest to a
    readership estimated to be in excess of 300,000.

  More specifically, the misc.forsale groups were created to
    promote individual-to-individual sales of items the seller
    doesn't need any more, as you might see at a garage sale.
    The moderated biz.marketplace groups, meanwhile, are
    specifically for continuing enterprises--companies,
    organizations, and entrepreneurs--who offer special
    opportunities to individuals and other businesses.

  The purpose of the Usenet Marketplace is to facilitate
    transactions.  The Marketplace is *not* your local paper's
    classifieds, despite the similarities.  Because of this,
    please keep in mind the potential interest of the readers and
    post ads for their benefit, not yours.  After all, they are
    paying for _your_ advertisement.

  Finally, if you are *browsing* the Usenet Marketplace, you may
    want to check out both the misc.forsale group and its
    biz.marketplace equivalent.  Even if you're looking for
    something used, it can often be found for less from
    commercial sources.
