Shop

Shops are sometimes generated on normal levels. The minetown in the Gnome Mines will always have shops. There are several types of shops:

 * lighting store
 * spellbook/scroll store
 * general store
 * grocery store
 * weapom store
 * armor store
 * (please correct/add more)

Shops provide:

 * (most obviously) items to purchase
 * items that can be stolen via help from a pet (combo w/ a lease or magic whistle for best results)
 * help identifying items based on their price (stand on a square with an item and #chat, cross reference with item spoilers for price listings/groupings)

A powerful pet or player can kill a shopkeeper, but you would forfrit the above benefits.
