I totally agree. Especially vendors, this should be a standard for online vendors.
Scott, there is an orchid site,
www.orchid.org, that rescues orchids such as you mention. They take donations from vendors, etc., but also take in the orchids that people buy just for the flowers, or all of those orchid gifts out there that never get taken care of. They nurse them back to health and then sell them to raise funds for non-profit grass-roots AIDS/HIV organizations, such as the one I work for.
Although they don't give us any money, YET.
It's in CA, but I bet the concept would work elsewhere.
