I put these on before speaking with vendors, and it improves both buying and selling prices.Īs an experiment, my character with 3 CHA sold some items without the CHA equipment (3 CHA), then I loaded and sold the same items with the equipment (7 CHA).

Much like raising intelligence for additional xp, you can raise your charisma for better prices. Fallout 4 has been in the hands of gamers for a couple of days now, plenty of time for people to compare and contrast the game on different platforms and hunt down early bugs or glitches. Shopping at vendors that give you a discount will help. Some vendors will give you discounts for actions taken in the game, like Carla giving you a discount for making a sarcastic remark when you meet her. Obviously there are ways to increase your income, but I'm considering that outside the scope of this answer, and focusing on getting better prices.
