I myself have put up something for sale that I was sure was "dear"
and "valuable" and "rare", and it got no bids at all. Obviously the
rest
of the world didn't agree.
Certainly telling the whole broad world that what you have is rarer
then hen's teeth and ultra-desirable is a common ploy, so common that
it means little.
I'm guessing that the people who use RK05 packs have metric buttloads
of them and don't need anymore, new or not. Certainly that describes
the existing RK05 users I know of.
