<blockquote><font class="small">In reply to:</font><hr><p>Product Listings
Sites devoted to the sales and distribution of a single product should be avoided, particularly if they are affiliate sites or if the site is merely a distributor for a manufacturer already listed in the Directory. The purpose of the ODP is not to replicate the individual listings of an online shopping catalog. However, individual product sites offering substantial information, tips, advice, and usage information for consumers are generally acceptable. <p><hr></blockquote>
According to this, then there should only be one site listed in this category. All sites in this category offer the same product and same information.
I also find that to be contradictory to the actual category description.
