You know how you can put stuff in an SDB and then set a price? OK, yeah … you probably do.
Now you can set a price on an individual piece of furniture as well. Then, other people can come along, click on the furniture, and choose to buy it (as is; with whatever upgrades have been added) for the specified price. That will leave behind a little "sack 'o currants" item for you to collect later.
So, if you have been selling furniture, maybe you'll make a nice little show room and then put all the components of it, priced, on another floor. (We thought about making it so that you could put and sell furniture in an SDB, but that was very complicated and not as nice as having the furniture visible and jump-on-able before you buy).
If you decide to sell some, post a link to your home street in here so others can check it out and see how it works.
