Schedule a yard or garage sale for later this month or next month.  Visit your neighbors and let them know what day you are planning your sale, and encourage them to have a sale on the same day.  You can all share advertising, put up lots of signs, and price everything to sell!  By mid June weather in almost every area is suitable for a sale.  Try to pick a nice weekend where there are very few other events.  Mark the date in your calendar, and start getting ready today
