A vending machines made their first appearance in v.0.030. They're blue and you can find those from Park, Silver Ruins and Clocktower. Chie can buy orange soda from vending machines. (Chie gets money by killing NPCs, which normally have 1/20 of chance, and some specific NPCs have 1/10 of chance, drops 100 yen.) There's three different kind of sodas, and their price varies from 100 to 140. Any type of Sodas increase max. "HP" (upper parameter in the Status screen) by 1, which don't have any significant meaning.SodaVending Machine fix'd
