I personally assess it's worth. If someone say, is selling 99 cokes at 500 each. I'll sell 10 at 600 each. That way, they're deal is actually better. But someone who only wants 10 will opt to spend 6k on mine.
Personally it doesn't bother me. I'm not some mega Omni Crafter king.

And I doubt if I'll ever be good. I just want gil to make my Auri glams as cute as possible. Because reasons.
