The base game only allows you to buy items for 120% of their value and sell items for 80% of their value and I feel that’s kinda bull****.
I thought back to the famously balanced game Oblivion and how it allowed you to buy and sell items for 100% of their value once you maxed out mercantile
and thought, “wouldn’t that be awesome to have in Fallout 4?!” (especially since money is a bit more useful in Fallout 4) and, upon finding out it’s like the easiest mod ever to make, decided to mod that into Fallout 4.
Now, with the right perks and a bit of charisma (and perhaps a little chutzpah), you can now buy and sell your items for 100% of their value! Wow!!
