shoptalk [item type]
This skill allows a Bimm to 'talk shop' with a general-merchandise shopkeeper and attempt to persuade the shopkeeper to check his/her inventory to see if an item of <item-type> might have been overlooked, and make the item available in the shop's inventory.
Individual shopkeepers can only be chatted up every 15 minutes. Extremely bad attempts to talk shop with a shopkeeper have been known to enrage the shopkeeper enough for him to ignore the player for a while.
Available item types are: weapon, armor, supply (i.e. medkits, flashlights, toolboxes), and miscellaneous. Items will always be normal items that you could find in standard shops.
