Canterbury Common: Investing in Traveling Merchants
Go to the area on the complete eastern side of the map in the very middle. You should soon discover a town called Canterbury Commons. Once the two costumed NPCs are done fighting, talk to the person named Uncle Roe. Choose to talk to him about the caravan merchants, then about organizing them into a special group. Once you are able to invest your caps in the merchants, the caravans will have better and more varied merchandise, while the merchants themselves will have better repair skills and more caps on hand at a time. Every initial investment in each merchant will cost 200 caps, while the second will cost 500 caps. With the Master Trader perk, each investment will be cut in half. You are only able to invest twice in each merchant. Once you fully invest in each caravan, the vendor will give you a special gift. Doc Hoff will give you several Stimpaks the next time you talk to him. The amount of Stimpaks varies based on your level. At the maximum level he gives you seven of them. Lucky Harith will give you one Mini-Nuke, Crow will give you his special Eyebot Helmet, and Crazy Wolfgang will give you a varying amount of Stealth Boys (at the maximum level he gives 6). The merchants and what they carry is below.
- Lucky Harith: Weapons and ammunition.
- Crow: Armor and clothing.
- Doc Hoff: Food and chems.
- Crazy Wolfgang: Miscellaneous goods and junk, also has best repair skill (at 75) when fully invested.
- Submitted By: Purple Haze.

Sell the scrap metal back to him repeatedly to get as many of those items as desired.
Fort Independence: Full armor and energy weapon repair
To get your armor and energy weapons repaired to full health, go to Fort Independence. Accept the technology side quest.
