Caps and vendors
Use vendor resets to sell more loot
Make additional sales when a vendor's available caps are not enough for a full haul.
Any accessible vendor with limited caps and a stock of items you can sell.
Repeat across vendor restocks, but the refresh timing is not specified here and may depend on game conditions. The amount earned is limited by both your loot and available vendor caps.
Stop when your caps target is met or the remaining loot is better kept or scrapped; use another vendor if you need to sell sooner.
Open a guide to find other locations and see what the item is used for.
