I have noticed that Marlin Flake, like a few other blends, for instance F&T Cut Virginia Plug, Dan's Mellow Mallard & Patriot Flake, Sillem's Councilor, RMc Scottish Flake, will all go through periods of scarcity. For a while I thought it was something having to do with availability of some of the ingredients. But I would imagine it has more to do with a combination of supply vs demand, popularity, or in the case of Mellow Mallard & Councilor a cult following that snaps up a lot of the limited amount of tins that are put to market. With Marlin Flake, I think it's a popularity thing. Lots of piper's enjoy it and K&K can't make it fast enough so there will be a period of time where the market is empty.
