Fallout: New Vegas merchants

Merchants can be found in various locations throughout the Mojave Wasteland in 2281.

Background
Some merchants move from place to place in the wasteland, but most trade from shops in buildings or settlements. In addition to normal traders, there are doctors who can treat various ailments for a fee; certain traders can also repair the player's equipment.

Prices for goods and services may vary depending on the player's Barter skill, and their reputation with a particular faction or community.

Merchants

 * Items sold to merchants will remain in their inventories until they restock.

Bugs
Merchants restock their items based upon the game settings "iMerchantRespawnDay1" and "iMerchantRespawnDay2" which are equal to 0 and 3 respectively. These equate to a Sunday and Wednesday day of the week. However, some NPCs such as Fitz and Lupe who are marked as "No Low Level Processing" NPCs are assigned not to run scripting unless the player is in the same cell as them (general area) at the time the scripting is called. This can lead to those NPCs not restocking their inventory properly.
