Undercutting.

[Charisma]

This same topic seems to come up once a week.

It's a Free Market. If you don't like the undercut, buy the undercut product and list it higher or move onto something else while the price normalizes.

This thread is not about undercutting itself, its about people who undercut themselves, even through it doesnt make any sense, no matter how hard they try to explain why.
