All good ideas. Especially about people coming early. I do not open the garage until posted time. Look out for busy groups of distractors, have people watching all around, do not let anyone in your house, post "not responsible for accidents", make your signs large and readable (saw one the other day on a pole along the road --typed!!), take them down afterwards, make signs colorful and simple, just sale and arrow is enough, be friendly and have a group sale or go together with others, have a chair to sit and rest, have a cup of coffee or drink or snacks for yourself, if you really want to get rid of an item price it low. At the end be flexible and give discounts. Afterward box the leftovers and bring to charity. Most of all enjoy.
