Each time i see someone not understanding how some people can cut prices so much and still make a living of it, i wonder where they live irl for not having any discount stores around them, and not even knowing what it is XD

Who do you think did make the more money these last days :

- me, selling each day several items stacks for 99 000 gils ;
- the other "but undercutting is bad !" players who price the same thing for 130 000 and didn't make any sales for a whole week ?

If in the merchant course you want in your first post, they are telling you that there is no money at all to be made by selling quickly tons of units at low prices to an extended customers base, and that selling less items at high prices to richest people is the only way to go, then don't listen to it, it is a bad one. Unless of course all these discount stores i see irl are some sort hallucination i have, and that in fact they don't exist at all.
