Answer 2

Depending on how far they live from the nearest town. They may travel be car if they do their shopping once a week. Some have light aircraft and their own landing strip so may go to a city when required. They can also get items delivered like TVs but only when a delivery truck is in their area. It all depends what they want and how for they are from the nearest town.
