In the near future, my wife and I will occupy a new rented house. First thing to do, is to fill the house with some home appliances. As a young couple, our financial condition is in recovery, so we have to spend our money wisely to buy them. One of the most important houseware that become our first priority is a refrigerator. There are various brands and types of refrigerator in the market. We need to select the most appropriate brand and type of refrigerator base on our needs and limited budget.
