Cap Collector (Fallout 4)

Cap Collector is a perk in Fallout 4.

Effects
Decreased buying and increased selling prices when Bartering.

Ranks
The effects of the first two ranks stack multiplicatively, giving a total bonus of 32% (1.2 * 1.1) for selling and discount of 28% (1 * 0.9 * 0.8) for buying items. In addition, rank two in combination with Local Leader rank two, allows for the creation of trade emporia, the highest store tier that can be constructed in settlements.

Rank three gives the option to invest in shops. For settlement shops, investing 500 bonus caps into their inventory applies to all instances and all tiers of that particular settlement shop type (weapon, clothing, general, etc.) across all allied settlements. However, bear in mind that these caps are shared, so there are only 500 caps to be obtained from each settlement shop type. The player character is not limited to their own settlement merchants, but can also invest in almost all of the merchants.
