Sell electronics on high demand
As you are aware, demand and supply are the rules of business. They determine your profitability and price. In this regard, you should analyze the demand and supply trends before deciding on the electronics to sell. Selecting a product with low demand means that you will take time to make a sale. This will lead to increase in cost due to holding stock and loss of value.
Also, your electronics will become outdated as advanced ones are being manufactured daily. To avoid such events, you should always seek to offer on-demand electronics.
