Potion Stand Story

You and your friend Elly are finally going to WitchCon this year — for real this time. There is just one problem: you are both completely broke, and tickets alone will cost 4,000G before accounting for travel, lodging, or food. Elly has a plan: set up a potion stall outside the local dungeon and sell healing supplies to passing adventurers. Starting with 100 gold, can two scrappy witches hustle their way to the convention of their dreams?
