I know that building the shops in your settlements allow you to sell items and are convenient, but do they allow you to make money?
Do I need to take a certain perk before I can start making money?
Can I make money only with certain shops?
Do I have to invest in them before I make money?
If I CAN make money from them, how do I collect it?
Is it automatic every time I visit the settlement with the shops in them?
