It's tricky. How do you price a model kit so that your average consumer won't choke on the price, yet still make a profit while at the same time your consumer base is shrinking, not growing? Do you charge less per kit in the hope of selling more kits to fewer people and build sales volume that way... or do you charge more per kit because your consumer base is dwindling and you have to make more money per unit in order to survive? And if you go with the higher price business model, at what price point do you start actually killing sales?
Like I said, it's not that easy. I sure don't have the answer.
