Beside forge money and sell the redundant equipment(like the weapon),

I noticed the item crafted in the workshop that can be sold are profitable.

For example, use $550 to craft the flash grenade and can be sold $650. 100 profit / 12 hours..

In my game progress(Chapter 3), I find the most profitable item is the riot slug(used on the shotgun to stun), $215($755 - $540) / 13 hours, nearly $20 per hours. If you have a craft talent agent, even better, the time reduces to 9 hours, $20+ per hours profit.

Compare to the forged money, each agent $50 per hour(upgraded twice). It isn't overpowered but a little help.

In the early game, you can craft smoke genade(I remember it unlocked in Chapter 1), $155 / 12 hours(8 hours with craft talent). It's better than the decoy and the flash grenade.

Firearm Suppressor is also a good choice $150 / 10 hours(7 hours with craft talent, $20+ per hour)

Hopefully, it will help you.

Hmmm.. Interesting. Thanks.

I agree with you, It should be designed on purpose.

But I didn't realize that for a couple hours, because normally there is a very bad discount when you selling equipment back in many games. I'm inspired by the firearm dealers' report in secret file of the game, "why I can't be a dealer like them?"
Then I find that I can (partially).

By the way, thank for your extra info. especially UFO, UFO is almost the same age as me, I couldn't play it. Thanks for sharing.

Well, if we're selling weapons on the black market, the profit should be at least 100% :D

Well it's only for stuff you craft that you can make a profit - the sell price is still below the buy price otherwise.

My issue with buying/selling initially was that I actually didn't realise you could buy/sell. For some reason I expected a separate weapons dealer screen or something.

And yes I realise there's an icon that actually says "buy/sell" on it, but it will only display something if you either have it in inventory or can buy it - and then only of the appropriate category (weapons or equipment). If you click it without selecting a weapon or item slot, it displays nothing at all.

Even then, it was a while before it became obvious to me that item selection was limited and subsequently unlocked via rewards (from intel, missions, etc.). While the system does make perfect sense once you get used to it (and makes buying stuff while planning an op much easier than if you had to go to a separate screen), I wouldn't mind some kind of indicator/list/whatever somewhere that shows what dealer(s) you've contacted and what they offer - for immersion/satisfying my need to have everything documented if nothing else.
