There are all kinds of people, those that are real die-hard garage sale freaks and some that wouldn't be caught dead looking at other people's second-hand things.
One of the most difficult items to sell ar Christmas decorations. In summer, at the height of garage sale season, people aren't thinking about Christmas, but after early September, people have received their school tax bills and maybe feeling short on money. They are also thinking about saving to buy holiday gifts. The weather is also getting colder and folks don't want to stand outside on a breezy day when it 40F and look at wreaths and stuffed Santas.
