Trade Tables!
 

A nice piece of furnature, looks like a table but is for trading

You can then add one to your player-house store, and the owner can place items for sale on them.

Use commands like:

/setselltable sell itemname sellprice [plat|gold|silver]

the owner could pick them up for free of course,

or

/setselltable buy itemname [of material] buyprice [plat|gold|silver] qtylimit

the [of material] would be optional for things like stone, so you can say '/setselltable buy stone of stone 1 plat 10'
....so people don't sell their stone made of metal that you cannot use to build houses with.

so players can sell items too, if the owner left enough plat for purchasing.

(Note, if a player sells something, it would need to go into a holding place, not onto the table for sale, unless that item type was already on the table for sale.)

other commands:

/setselltable takefloat amount - takes money out of float for buying

/setselltable addfloat amount - adds money to float for buying

/setselltable collectbuys - takes items people sold that are not on table

....and commands I guess would only work when touching the table.

And when a purchase/sale occurs, the NPC server can PM the store owner if they are online.

If automation like that doesn't go over well, then how about being able to use them in conjunction with paying a NPC storekeeper a weekly/daily fee?

It would be more RPerly to hire a storekeeper, and then you have to make ends meet to pay your employee.

Or just have them work like the current market tables, except rent on them doesn't run out, and only the owner of the house can make any changes to it.

Both ideas rock

First idea is too complex, and the second im sure has been proposed alot XP

yes both are very good ideas, it has been meantioned in the past but no one has yet to pick up on it, at present i do not know how graal kingdoms is scripted in any way, shape or form to begin this task otherwise i would, perhaps others may take upon the task

Make it work O_o

Go Stefan Go!! O_o
