Ugh I made it half way. This thread is a mess.

"Undercutting" is a natural ebb and flow of a marketplace. It is frustrating, but it's not immoral.

You (and others) assess the value of an item at 1m. Someone comes along and says, I can afford to let this go for 950k because it will sell faster than these other guys. That's normal. His sacrifice is 50k gil. Your sacrifice for charging more is waiting longer. You could (as suggested) buy it and sell it at your price. Of course that is risky. All investments are risky. Spending 2m on mats hoping to get 4m returned only to find the price has dropped to 1.5m is a risk. We all take economic risks as buyers and sellers.

At any rate, if someone can afford to sell something lower by their estimation, then they deserve to have it sold first. The only reason this gets sloppy is when RMT get involved, because they can monopolize a market and crank out products 24/7 while the rest of us (usually) cannot work round the clock to produce high demand consumables or rare equipment, nor can we watch prices 24/7 to make sure we're always on the top of the list. RMT is the problem, but not a legitimate player who is using the market system to his advantage.

I think you guys are confused about where the problems and unfair advantages lie. Everything described in this thread is completely fair. You either match prices, buy them out, or wait longer. That's how businesses work. Well, businesses who can't use market analysis or advertising to push their wares faster anyway.
