Most people think about the cost of buying a refrigerator, but this tip is about saving money once you have a refrigerator. If your refrigerator is old, consider getting a new one that is more energy efficient. The savings over the long run can be huge and, wouldn't it be nice to have a new refrigerator? Also consider defrosting your refrigerator once a month and also be sure to clean the back of it (the coils) using a vacuum. And one other tip - don't stand in front of the fridge with the door open thinking about what you want to eat or drink. Think about it ahead of time so that you're quickly opening and closing the refrigerator. This can actually save a lot of energy and money.
