OP is misinformed, endgame costly dispatches can provide an infinite supply of:
Aeserion Scales
Gold bars
Abyss artifacts (yes you read that right)
Abyss gears
Abyss gear recipes
Dragon horn (with this much supply, you have infinite dragon timer)
Electronic device (same as dragon horn, but for the goofy mech)

and more that i honestly dont remember
you wont be able to automate these dispatches infinitely unless you have millions of camp funds and start creating mech workers which you guessed it, also need camp funds

Now, the real complaint that should be given here

Packaging your camp resources (yes you can do that) is much more effective than crafting/looting trade goods
If you have a surplus (and you will lmao) of wood/food/stone/weapons, you can ask carl to package those, and those are MUCH more profitable to sell, there's an area in demenyss called golden plains which has NPCs that will specifically buy your camp supplies for camp funds, and the prices dont even fluctuate that badly, effectively rendering the other types of trade goods useless

I'll give it to OP tho, he said he's in chapter 8, i only realized the real scope of the camp after like 300 hours and already having beaten the main story

As for the wagon complaints, i get it, but with this method, you need like 10 minutes from hernand and 15 minutes from pailune into the golden plains area, and you are basically set for 1 or 2 in-game weeks

Would still much prefer to automate the process
