Would there be anything else to do to make it as gentle as possible for the search engines?
You know all those people who write in to Miss Manners asking how to break up with their boyfriend without making him feel rejected?
Can't be done. Sooner or later you have to tell the search engine it's gone.
Isn't there any possibility of keeping the page for information-only rather than for sales? If it's still got significant links and search-engine traffic it must be providing something of value.
