Pierre's General Store - Stardew Valley Wiki
Pierre's General Store is one of the first locations the player will visit in Stardew Valley. It's where you can buy various seeds, saplings, and items. After you have 8 hearts with a single villager, a bouquet of flowers will be available for purchase (however you can only give these to marriage candidates). You can also sell Pierre foraged items and crops if you need instant gold and don't want to wait over night.
