Zero, Link is talking about the price it sells for in Hyrule. I know that it canonically isn't possible for Hyrule to have Chateau Romani, but I was figuring a little fanon wouldn't hurt, where Termina is on a far-off continent from Hyrule. Therefore, the import and transportation fees would be implemented. I'll change it so it wasn't so outrageous, but that's what I was thinking when I made that post.
