Demo: how do you buy stuff from other factions

[RDB92]

Still playing demo, and I really like the game. But I need to know how you can buy stuff from another faction. I'm now playing Arroyo, and I have a trade contract. I can sell things with my storehouse, but how do you buy goods?

Take your knight to the village storehouse you want to buy from.
