There's a forum for moanin' and groanin', where such discussions should be carried out, for sure. But it's hard to know when to go there when a discussion isn't yet a full-on discussion. I think most realize that shitting in a sales thread is the biggest no-no there is. Everyone has the right to sell whatever he/she wishes for whatever amount. But that right is subject to the unfettered verbal review of others.
There's a doctrine in law called the "reasonableness" doctrine. While it obviously doesn't apply here, I think most of us have some kind of "reasonableness" doctrine we live by. In my case, the amount being requested violated my own "personal reasonableness doctrine". Having said that, I plan on adding nothing else concerning this subject. Frankly, I had hoped to wake up this morning and not see any further discussion of it.
