Fell & Sell does not ask you to accept a fixed vendor price. You control the tags, while supply, demand, shop prestige, and decoration bonuses shape what the market will bear.
The confirmed variables
Official store information names current supply, demand, shop prestige, and decoration bonuses as pricing inputs. It also states the basic consequence: goods gather dust when prices are too high, while prices set too low can push the business toward bankruptcy.
Start with the interface
Use the live game's price information and demand signals rather than importing a formula from another shop simulator. Version 1.4.2 turns the price text red when a tag is 10%–33% above the acceptable price. On the first load after that patch, severely overpriced existing items are adjusted once to a random acceptable value—not to a guaranteed maximum.
Change one thing at a time
Price a small group, observe sales, and make a measured adjustment. If several variables change together—new decor, higher prestige, and a large price jump—you cannot tell which caused the result. Keep notes by item and version.
Balance margin and turnover
A high margin is not useful when inventory never moves, and rapid sales can hide weak profit. Consider shelf space, replacement difficulty, current demand, and whether the item is needed for crafting or equipment before listing it.
Use decoration intentionally
Decor can improve sales appeal while also granting expedition buffs. A layout therefore has an opportunity cost: the best commercial arrangement may differ from the best combat preparation. Test both the customer response and the next run.
No complete formula yet
The official patch now documents one numeric warning band: 10%–33% above the acceptable price turns the text red. It does not publish the acceptable-value calculation, demand multipliers, prestige thresholds, decoration percentages, customer patience, refresh timing, or optimal markup. Do not turn this UI cue into an invented price formula.
