I don't get it. When you sell something to the current pnj, you can also set your price. What would this pnj you're proposing change? Is it the max price that doesn't seem high enough? In that case, it might be possible to raise the current max % even higher, without having to create a pnj for that.
that's right, you can go up to 9999% but the price isn't enough, for example you can't sell a maga amp because the price the p,j is offering for resale is really derisory compared to the price of the mps :)
