Stardew Valley Farmhouse Mailbox Guide
After the farmhouse is repaired, the mailbox upgrade costs 5 Golden Walnuts. It lets the player access mail from the island, and undelivered mail can be retrieved from either mailbox regardless of where the player slept.

Checklist
- Buy the mailbox when island stays are long enough that mainland mail trips are annoying.
- Use it before multi-day Volcano, farming, or Golden Walnut cleanup sessions.
- Remember this upgrade is also required before the Farm Obelisk can be built.
