Interesting. Not a complaint - I haven't used any of their stuff yet - just an observation.
You'd think that if half their powders fit in a bottle half the current size that stocking and using 2 different sizes would cost less considering they're shipping so much air. A general rule in manufacturing is to pack into the smallest size possible to maximize carton/pallet/trailer/container space.
You'd also assume a lot of LGS wouldn't stock it or at least as much since most are tiny to begin with and tend to pack their shelves densely. If I had to choose what to stock on my shelves, I'd go with the stuff that took up half the shelf space unless my customers insisted I carry it. Of the 2 LGS near me that I use, one has it out on the shelves with everything else - they just put it on the bottom with other larger items. The other keeps it in the back but has IMR, Hodgdon, Win, & probably a few others out front where customers can see it. I would assume the 2nd shop sells more of the powders that are on display vs the stuff people have to ask for. Maybe not.
