Trying to understand player behavour with MB & MSQ dungeons

[Kamatsu]

Nope, that is assured more Gil for me buying from the board and selling to npc. Happens with higher priced items too, and I'm totally fine with it!
Especially with people that forgot to add one '0' at the end...

I'm talking about the seller - it's a complete loss for them, as they are selling it for less than they'd make selling to an npc merchant, as well as paying tax on the sale so even less!
Obviously for ppl who buy it and sell to an npc or relist it, it'll be profit for them.

As for Alleo's comment - indeed, it's why I've not done it. Considering the times I've come across it being done... hasn't generally speed things up, I just never saw the point (once cutscene's were unskippable) to doing so... risk your account being suspended to save a few minutes? Pffft.
