Garage sales are an easy way to make money. A garage sale is also easy to setup. All you need is to go through your old stuff that you don't use anymore to create an inventory. Next expand your inventory by asking around to see of other people have things that they don't want that you can have. Once you have enough inventory decide on a day to have the garage sale. Next make flyers to advertise the garage sale. Finally price your item approximately and then what for the day of the garage sale and make money.
