Fast route
Do this in order
- Step 1
Save high-value produce, artisan goods and safe duplicate collectibles for one large shipment.
- Step 2
Load Chester with items whose combined sell value is over 9,000 coins in the same night.
- Step 3
Sleep to resolve the sale; the achievement checks the completed shipment, not the value shown while loading.
Prepare before you start
Keep spare materials, coins and one free inventory row. For cumulative goals, use the collection or status menus instead of guessing from a single night.
