Stalls should be able to buyout stuff aswel, according to owner price and demand.
It`s not likely that new character that working on their stats have money to get stall and from other side, without stall its hard to accumulate cash for eventual future one. If owner of stall have ability to buyout certain good that he demand lower players would be able o focus on that production and earn some money to spend or stash. I`m playing for a month and stashed loads of decent value materials that i would sold dirty cheap to stall but not feel like hanging in Boston and yell and attract scammers (like i already did once).
