I think appropriate purchase price is the value placed on materials and labour to make the item.
On the other hand, if an item is priced more than the reasonable selling price, then the seller is profitering.
It is not a question of haggling, but a matter of attitude. The old man showed his dislike to Rin, and tried to take advantage of her. The price he qouted 300 was for a level 1 potion while she was selling a level 3 potion.
For all that she knows, he could be buying the potion from her for 300...

@DeathDonut most of the people in the story only have magic power in the double digits. I don't know if it has been shown in the manga, but in the webnovel he had made a magic power measuring device that is capable of displaying three digit values but it still showed his magic power as 002...
Asimov three laws

Actually, this is a modified inteperation of the Yuki Onna lore, where a Yuki Onna would melt due to love. By the way, names such as Yuki Onna should not be translated unless there is a specific word that describes the same thing such as neko, cat, kuching.
@nomadicengi different countries, different laws. From what I could understand his second marriage was in Malaysia.
From Islamic law point of view, a muslim can marry anyone from any religion of the book but is not encouraged to do so.
Wheather they can do that is also dependent on local laws.
