Shop command
The SHOP command allows you to see the wares in most shops. You can type SHOP by itself to view the the items that hold goods for sale, and you can also type SHOP <ITEM> to view the goods for sale on it. Finally, you can type SHOP <GOOD> to view basic information about it, such as where it's worn, what it looks like, and how much it costs.
This also works on Trader Market tables.
Since you are on a newer Front End, you can open the Shopping window and view all of the output in there. To do this, type SHOP WINDOW.
Additionally, if you have links turned on, you can click on items or goods in the window to use the SHOP verb on that item. If you click on the topmost link, it will take you back to the previous list.
Traders who own shops in market plazas are able to use special owner only SHOP commands to interact with their shop.
