It's a flaw in the design of MMO market boards because it encourages people that market board camp and just continue refreshing their items to be the top. They may as well just give the retainer an option to repost your wares down to a fixed minimum value. I mean that is effectively what MB campers are doing.
Undercutting is fine if to drives prices toward equilibrium, but when people are undercutting by 1 gil it's doing this in the slowest most tedious way possible.
