Barter (Fallout: New Vegas)

Barter is a skill in Fallout: New Vegas.

Description
The Barter skill is primarily used in the buying and selling of items, such as trading with a merchant or scavenger. In general, purchase prices will be lowered and selling price will be higher. It is the primary factor in price determination, and is also offset by the Barter skill of the non-player character in question. The skill is also used in certain dialogue options with non-player characters, where certain responses require Barter checks.

Initial level

 * $$\text{Initial level}=2+(2\times\text{Charisma})+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Charisma of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=2+10+3=15$$

Barter affects the prices gotten when trading with merchants. There are also many Barter skill checks in the game that can help advancing in quests by displaying a good sense with money, talking down costs, and talking up rewards. The Barter skill is governed by the Charisma attribute.

General price (before application of reputational fees or discounts) is counted with the same formula as in Fallout 3. Note that reputation does not affect prices unless that particular merchant is scripted to modify worth based on the Courier's reputation. For example, Chet will only use the PC's barter skill value to determine prices even if they are Idolized with Goodsprings, but with a mixed reputation (regardless of how good or bad it is), he will offer at 1:1 prices.

Barter in quests and exploration
While hard to tell in the abstract from the following list, in many cases Barter is offered as an alternative dialogue skill check to Speech (though generally involving paying money) or other skill checks. This may be to help compensate for the fact that Barter on its own may not be as useful as other skills.

Available discounts

 * Goodsprings: Trudy will give the Courier a discount for saving the Goodsprings settler during Back in the Saddle, repairing her radio or helping the town during Ghost Town Gunfight. The discount is tied to becoming "Accepted" in the town, not any one specific act. The discount will be lost upon gaining infamy.
 * Goodsprings: Chet will give a discount with a mixed reputation in Goodsprings, but doing so will void the discount with Trudy. However, Chet has a much wider inventory and more caps than Trudy, making him arguably better for trading.
 * Goodsprings: Chet will give a discount after passing a Barter check of 25 if accepted the offer to help Joe Cobb take over the town.
 * Primm: Johnson Nash will give the Courier a discount for making Meyers sheriff.
 * Novac: Cliff Briscoe will give the Courier a discount only after speaking to Jeannie May Crawford about the Dino Bite gift shop and then telling him she sent the Courier. The discount will not be lost even if he finds out they helped kill her.
 * Old Mormon Fort: Julie Farkas will give the Courier a discount when they become "Accepted" with the Followers of the Apocalypse, further discounts resulting in 1:1 ratio when they join the Followers.
 * New Vegas medical clinic: 1:1 ratio when the Courier joins or becomes "Accepted" by the Followers.
 * Great Khan armory: the Great Khan armorer will give a 1:1 price ratio when Great Khan reputation becomes "Accepted."
 * Camp McCarran concourse: Dr. Kemp will give the Courier a discount if they help during A Final Plan for Esteban. The discount will be bigger if Christina is not asked for a reward.
 * Camp McCarran concourse: William Farber will offer the Courier a discount after repairing the food processor during Not Worth a Hill of Corn and Beans.
 * Hidden Valley Bunker: When the Courier's reputation with the Mojave Brotherhood becomes Mixed, a paladin should approach them and inform them of a discount. This is currently bugged, however, so only the reputation discount is available.
