New to this game and flipping from rookie to wastelander depending on encounter difficulty but I can't help feel I'm missing something cash flow wise. Really having a blast and want to get good enough to pump up to higher difficulties at some point.

I have the barter perk for selling junk, I'm about level 15 and just hit union station but I've never more than 3k on me at any given time and at the moment I've got about 600.

I've done every single side quest I've come across but certainly have never had enough money to keep all party members in level appropriate armor and weapons.

Wondering if there's someone I can grind for money or anyone has general money making tips?
