Blood In the Water:
Posting availability of newly released or rare tobacco(s) online, but only after personally securing as much as a strong man can carry, triggering a feeding frenzy (like sharks, pirañas, jackals, or vultures). Announce how much of the Unobtainium may still be available, to whip the frenzy. Bragging about the number of tins, pouches, or pounds purchased is mandatory, as is weeping, lamentation, & gnashing of teeth from those who missed out. (Special subsection for Esoterica Blends, particularly Penzance, may be considered).
