Let players buy back what they just sold, without making free money

Everyone sells the wrong thing by accident, so a shop should hold it for a short while. Done carelessly, that list lets the player earn gold from nothing or loses a quest item for good. Here are the rules for price, space, time limit and things that may never be sold.

Why this works

A safety net must be free of profit and free of loss. Charging exactly what the shop paid makes the trip there and back neutral, and a short list with a time limit keeps it a helping hand and not a second storage.

When not to use it

Skip it in a game where choices should hurt, such as a survival game where a bad sale is part of the story. Also skip it where the player may sell for whatever price they like; there the neutral trip no longer holds.
