Concept:Mobile shopping involves selling goods from a movable vehicle that travels from place to place.
Explanation:A mobile shop is a motor van or a large vehicle that has been specially converted into a shop.
The seller stocks goods inside the van and drives it from one location to another.
At each stop, customers can buy goods directly from the vehicle.
This type of selling does not happen at one fixed spot in the city.
It is not restricted to multiple permanent shops only.
It is also different from selling through a vending machine.
Therefore, the key feature of mobile shopping is selling from a motor van.
This makes the business mobile and brings goods closer to customers.
It is commonly used in retail trade to reach different neighbourhoods and markets.
