are they really worth this much?

Regular bandaids, which are what you have to stock in the fountain to get the enhanced bandaids, go for 8 GP each on average (1 piece of cloth = 1 bandaid). So at regular bandaid prices, 30K bandaids would be 240K. Each fountain can make 10 enhanced bandaids per day.
