Player shop is a marketplace to sell their items to other players.
All players have the option to "Setup Shop" from their inventory.
You can add items from your inventory and set a price you want to sell the item at and they will appear in your shop.
When another player taps on you, they will see a "View Shop" button on top of their screen. Using this button will allow the other player to browse your shop and buy any items you have setup previously.
