It unironically was very easy for me to afford due to being a chronic soloer. Made around 10-12 potsherds before I messed up on a floor mostly full of harambe and gloom (177). If anything I think I was positive even on sustaining potions.

Granted I am an outlier and have 698 potions currently with... 131 potsherds in storage. While I wouldn't be opposed to it having cost pumpkins or crests, potsherds are not difficult to acquire. If you're complaining about that then you're essentially complaining about having to put in work for something.
