Well there are products out there that the reason for increasing its price is because of a price increase of another commodity. For example, public transportations increase their prices because of increasing gas price, also electricity, food prices, some because of gas some because of the scarcity of resource, specially rice in some countries.... The less people can afford transportation, the higher the costs of commodity get... in short People don't transport goods as often as before nowadays. scarcity and high gas price..
