Most things have been covered already by others, but I wanted to add a comment. We lived in the Sun City area for many years before we retired and some of your buyers will be "different" than those found in other parts of the country. One method of "shopping" that was used most often by buyers is to arrive in groups (especially family-aged groups) and spread out over your sale area. That way they are able to distract you in one area while another person in their group helps himself to things for free. Unfortunately, having extra helpers is almost a must for yard sales these days. Hope your sale goes well and you make lots of $$$$$.
