By using this method, it is possible to repair any and all items to the player's current repair level without using any of you caps. To do this you, need the Confirmed Bachelor perk and enough caps to cover the repair cost of the item. When you arrive at the Mohave Outpost to get the pardon for the new sheriff of Primm, during the conversation with Major Knight a Confirmed Bachelor speech option is available. Select it, and whenever you do repairs through him, the item gets repaired to your repair level but the caps do not get deducted from your stockpile. This can be very useful when combined with any unlimited caps trick, and results in your player having all items at 100% condition (even things like the Fat Man, where replacement parts are difficult to find).
