Due to the fierce competition in the Pharmacist industry, everyone is undercutting each other to capture the market, causing profits to be significantly reduced. Even the Starry Night Potion Shop has had to attract customers with low prices. Among the Pharmacist's client base, large guilds are the biggest consumers. They have money and often purchase potions in bulk to save on guild expenses. Because they buy in massive quantities, they desperately try to lower prices. Those ordinary potion shops, to secure a big order, are willing to accept even very low prices from guild customers, eking out profit through volume. Some shops are even willing to take orders at a loss to attract long-term customers initially, showing just how intense the competition is.
