As posted by Hero on a reply to CfC post he would like a flea market, and had some ideas on how to do it.
i think it would be better to move it here
but yes.. in general cant trust people to leave stuff alone if unlocked.. in my opinion it should be done with vendors as its safest.. and people wouldnt have to bring cash along with em, can withdraw from bank. which is handy.
can stuff subbags with up to 125 items on a vendor so makes for good holders too, and people should be able to get rentals for free there. maybe custom a house for max floor space on all 3 levels. so people get some display items too.
idea is definetly possiblle, just need a few details layed out..
