Why is there a limit to how far away I can see items for sale?

Reshopper is based on the idea that it should be easy to buy and sell children's things that you can easily pick up in your neighbourhood. This means that trading takes place face to face, where you can see the product before buying and the seller gets their money immediately without needing to take a trip to the post office and send the goods. However, you can move around on the map in a radius of 20 km, so you can plan purchases when you are at work, on a trip or visiting family.
