High Demand Low Supply (HDLS) is an economic concept that refers to situations and products where there is a large demand for an item but the supply of that item is restricted and unable to meet the needs of the market. HDLS creates opportunities for businesses to take advantage of the higher prices that come with the scarcity of goods, as people will often be willing to pay more if they are desperate for something. There are a few different types of HDLS products, such as luxury items or limited edition releases, but the common thread between all of them is that the demand is much higher than the supply.
