Shop desk
 

should be able to put a shop desk/counter in your house, that only you can get behind ya know, just foorrrr fun heh

Better yet, you should be able to buy shop house flags :D They could be designed like a shop and you can put the items on the tables

Err, but who's going to want to haul their fat rear all the sodding way to your kingdom's main island just to go to your shop-house? People are reluctant enough to visit the market stands...

mm funny, almost every samurai hangs around samurai island =P

must suck to be you guys heh
