Please fix constant undercutting & with multiple retainers

[Palian]

As mentioned above you can't buy and sell those items for a profit because the supply far outreaches the demand and you also have to account for tax on top of that.

Wouldn't that indicate that even the undercut price is still too high?

It's a long game of patience where the reward is a monopoly over said item(s) if you succeed in driving off competitors. Most people simply don't have the capital or determination to sell 5 items in a row for virtually no profit. It's dirty ... but it works, if you have absolutely no care for the economy as a whole.

That might work, but unlike in RL, it's not a stable monopoly because in game, there are no entrance barriers (in form of upfront costs like machinery etc.) to get back in the market, if it seems profitable.
