One thing good to know is that when you ‘bulk’ your scrap stuff at a Tinker station, it does not go back into your stash, and if you get killed before you notice that (as you meander happily through the wasteland, satisfied that you took care of your junk in a responsible manner) it is really important to go back and pick up your ‘dropped junk’ as it is ALL of the bulked stuff. Learned this when it happened to me. I almost didn’t go back for my stuff, I don’t always have enough scavenged stuff to make it worth the effort of going back to get it. I fought my way back, hovered my arrow over the bag and was like HOLY HECK! I had bulk springs, screws and more that dropped.
So yeah. Also, bulk, then sell. I bulk all the things, but only sell steel, wood, basic things. Maybe do that at WhiteSprings. Also, Whitesprings vendors are not connected to Flatwoods. Just another FYI.
