Get Your Perks Right
Much like we suggested in our guide on how to level up faster, we’re going to suggest focusing on your perks here. For anything money related, you’re going to want to focus on Charisma and Luck for the most part. The very first option in the Charisma tree for your to use as a perk is the Cap Collector perk. Not only will this mean that you won’t have to pay as much for the goods you purchase from shopkeepers on your travels around the wasteland, but you can also sell your items for more.
Pour enough points into the Cap Collector perk and you’ll be given the option to invest 500 caps into a marketplace. In doing so, you can raise a store’s buying capacity. However, we’d suggest leaving doing something like this until you’ve got a fair few thousand caps.
The other perk you’ll want to take a look at is in the Luck perk tree, called Fortune Finder. You can invest up to four skill points into this perk, with additional point increasing the number of bottle caps you’ll find in containers around the world of Fallout 4. Max out the Fortune Finder perk and not only will you max out the number of caps you’ll find in containers, but enemies also have the chance of exploding into a shower of caps when defeated. This is a no-brainer for you to invest in if you need the caps, and will definitely combine with the other suggestions in our list to really maximize the caps you can find in the game.
