They are not reasonable - they are killing my shop...

I have to buy food, and pay for heat, water and electricity, while I have to constantly stock raw material and buy new equipment. I sell most of my armour far under value, either because I was late with them, or I desperately need that money, or simply because I'm not famous, and mostly, because I'm in Hungary, and sell only to Hungary. Even a good SCA level armour sells at $2-3000, but I could get less than $800 for the very same, while MacPherson, the very best modern armourer can ask for 20K as a start.
And because of this, I have to stick to munitions grade stuff... where function is more important than anything else, and production cost can be kept at a minimum. If someone wanted to pay even 10-15K for a vollharnisch, and would be able to wait for a year or so, I could even make Negroli-level armour, as I have the tools and the skill as well... but for 800$, I won't.
So if anyone is interested: the correct price for that fluted vambrace should be at $100-120, the helmet about 150, and the krug is correct at 225. A correct, munitions grade barbute (italian classic-like helmet) would be about $400. Riveted mail doubles the price, while blackening adds 50%.
