So can you mail things to certian locations? If so, how do you do this. Maybe other people who do not know abou this will learn something new now.
Once you discover two or more Mohave Express mailboxes, you can mail items to yourself to be picked up at the other location by you when you get there. You can tell if you have something waiting for you because the little red flag on the left-side will be sticking up.
If you're playing on hardcoe mode, this is extremely useful because more things have weight (ammo). So I'll ship all ammo that I'm not currently using or any excess ammo back to wherever I've called home. Or if you like crafting foods / ammo / weapons, you can scavenge (er, "prospect") to your heart's content, then send it all back to your home base location via the Mohave Express rather then traveling yourself. Travel is more of an issue in hardcoe mode because it takes time and that means consideration of food/water/sleep needs and supplies. So I don't fast-travel back to my home base just to unload junk because it's a waste of food/water. Or if you like creating food with the Survival skill, you can go out hunting, then mail a bunch of raw meat / berries / twigs back to your home location, then go hunting some more.
It's extremely useful. Personally, I base out of Goodsprings, because there are (2) dumpster containers right by the Mohave Express box, which means I can unload right from the mailbox into a pair of containers. And the ammo press / repair bench are right around the corner.
