The term DECLINE IN PRICES can be summarized as a decrease in the cost of goods and services. This is often seen as a positive sign for consumers, as it allows them to purchase more with their money. The acronym SAG stands for 'Supply and Demand, ' which is an economic concept that explains how prices are determined by the balance between the amount of goods available and the amount of people wanting to buy them. When the demand for a product is low, the price will decline.
