I'm looking for a mod that allows users to set their own custom prices through an ini file. Would this be possible? For instance, I could change the price of the meat I get from animals, the value of their skins, the value of their claws. I could set my own food prices. Basically an ini file that has all the prices in the game and you can go through and change them. If not, anyone know how I could manually change prices? How difficult of a process would it be?

Hey I'll try to help you out. Give me about an hour or maybe two to get woke up. I think I may can help you with this.

But wait, you can't sell those items at a fence already? 

I'm still learning myself but I'm a quick learner and for one thing I try several things out over and over, modifying one value at a time and monitoring changes, rinse and repeat. If you create backups, it's totally safe. I mess my game up all the time by modifying the wrong values are setting a bad value. I just copy over my backed up file, replacing the crappy one that I messed up and I'm back for Round 2 :) 

I'm not TOTALLY sure but I think it may be like this

> Items that are already in the catalog and that can be sold, can EASILY be modified. You literally change a value to what you want, save the file, quit. It's really easy.

> Items that can not be sold have a few extra steps that need to be taken. If you're a noob to modding it might be a bit of a pain, but I'm going to try simply adding sellprices to cocaine_gum and see what happens. If it works you're in luck as that will not be hard at all. 

I'm not sure about the second > point. I will test it out right now and find out. I'll start with COCAINE GUM! lol 
 

Thanks dude. Yes by default, cocaine gum, chewing tobacco,  cigarettes and premium cigarettes CANNOT be sold. Only bought. Which really was annoying cause buying them is expensive as hell (6 dollars for chewing tobacco?). If you try to sell them it always says the shopkeeper is not interested in this item and has 0.00 dollar value, which is what should be changed as well as perhaps adding a shopkeeper that is interested in it somehow. I would also love to sell opened gin and opened kentucky bourbon or opened fine brandy in addition to cocaine gum, cigarettes and tobacco. Basically I wanna make Arthur Morgan a drug dealer lol.
