There are a few rare crafting items you might want to hold on to. Only pick up craft goods with intent to craft a specific thing usually. You'll be Rolling in Caps when you get around to maxing barter anyways, and weapon repair kits are generally a pain to make after you get Jury rigging.
so you'd only need to craft to fit your own personal needs, which aren't that high considering how much stuff exists in the wasteland.
