What to do
- Finish the current sale sequenceKeep selling until the center-right Perk Meter reaches full. The filled bar is a readiness signal, not the perk itself.
- Walk back to the cash registerMove to the register at the shop counter. Do not wait for a pop-up to appear while standing elsewhere in the shop.
- Interact with the registerUse the interaction prompt shown for your platform. A current player report says this is the step that opens the perk choice after the meter fills.
- Choose one offered perkSelect the temporary shopkeeping perk that fits your current selling plan, then confirm it. The sources do not establish a universally best choice.
- Verify the meter and perk stateAfter confirmation, check that the meter has reset or advanced and that the chosen effect is shown in the shop interface.
How you know it worked
The meter resets or advances after you confirm a choice, and the selected perk appears in the shopkeeping interface for the current run or sales sequence.
Platform and version boundaries
| Full meter | It means a perk selection is ready; it does not automatically grant a perk. |
|---|---|
| Trigger | Interact with the cash register to open the choice according to the current player report. |
| Duration | Developer material describes these as temporary shop perks rather than permanent character upgrades. |
| Controller | Use the interact prompt shown by the game; no controller button is guessed here. |
Common failure branches
- Stop and verify: If the register interaction produces no choice after a reload, record the platform and build before assuming the save is broken.
- Stop and verify: The current evidence does not rank the offered perks or prove that every perk has the same duration.
- Stop and verify: A later patch may change the UI position or wording even if the register interaction remains the trigger.
Evidence note: A current player report identifies the missing action at the cash register. An independent Steam guide locates the Perk Meter and explains that it tracks the next shopkeeping perk; developer material independently confirms that shop perks are temporary choices.
FAQ
Why did nothing happen when the meter filled?
The full meter only makes a choice available. Interact with the cash register and select a perk manually.
Are shop perks permanent upgrades?
Developer material describes them as temporary shop perks, so do not treat them as permanent character progression.
Which perk should I choose?
The evidence confirms how to claim a perk, not a universal best choice. Pick for the current selling situation.
