You can sell a variety of items including rare collectibles, vintage products, and everyday goods. The specific items depend on what you acquire during the game, so keep an eye on what’s trending among customers.

Efficient inventory management involves regularly checking stock levels, knowing what sells well, and ensuring that you re-stock popular items frequently. Use analytics to track sales data and adjust your inventory accordingly.
