Responding to a post that's no longer there, suggesting I was supporting resellers with this change:

Right now, people pay resellers up to 40 million gil for small houses. If you can buy something for 3m and sell for 40m, it's worth selling. If you can buy it for 40 million and sell it for 40 million, it's not. Upping the placard price kills the profit, kills the market.
