Why does a shopkeeper keep deflated footballs instead of inflated ones?

A shopkeeper may keep deflated footballs instead of inflated ones for several reasons. Deflated balls are generally easier to store and transport, taking up less space and reducing the risk of damage during handling. Additionally, selling deflated footballs allows customers to inflate them according to their preferred pressure and ensures they meet personal or league specifications. Finally, it can also lower shipping costs, as deflated items are usually lighter and more compact.
