Weston Shooters Club listed primers for what they felt their opportunity cost was. When they said "not worth selling at $100" they did not mean "$150 profit is not enough" but rather "At $100 we feel it is more advantageous to keep in our inventory to support making ammo for our members than depleting our stock as we do not know when we will be able to place a new order, or how long it will take". Unfortunately, they did not make that point clear and people actually thought they were trying to make a killing on the 1M primers, initiating much NES invective replete with unflattering innuendo.
It's like my Serbu 50BMG (50A, not the model that blew up). There is a price at which I would part with it, but I am not listing it because I would look like some fort of deluded arbitrageur. Ditto for what it would take to buy my house now.
IMO their mistake was not simply taking ownership of their price. All they had to do was come right out and say that instead of like wussing out and editing a post and all that stuff.
I recently told a rando outsider that was begging for help that I wouldn't work on a consumer laptop for anything less than $10,000.... I also said simultaneously that I realize the price for that is insane, but you have to take the perspective that basically you would be paying for all the time/money losses that I've incurred in the past 20 years in terms of touching these types of laptops. It's literally not worth it.
