The sticker swap — Trading Post · Demand & Supply
Leo is swapping football stickers at school. Help her make swaps that are fair to everyone. Make the best choice at each step.
Your task
Make the best choice at each step.
- A swap is fair when both sides know what they give and get, and nobody is tricked or pressured.
- Invented stories to learn from. Prices and shops in them are made up, and this is not financial advice. Ask a trusted adult before buying or selling anything for real.
- Never share personal or payment details online. Nothing about you is collected.
Score
- Understanding trade — You understood how this part of trade works.
- Wise choices — You weighed your options before choosing.
- Fair play — You treated buyers and sellers fairly.
In real life
Rare stickers are worth more because fewer exist: that's scarcity, the same idea behind many prices.
