As far as advertising goes I always make sure that there are signs readable from all directions at all major intersections around where you live and also at the half mile intersections also. Also make your signs distinctive from other signs that might be up in your area. You will get a lot of people who what something for nothing almost. If someone makes me an offer on something I will counter offer. I also will not take the first low ball offers just to make a sale. I will keep trying to get the most I can as usually more than one person will have an interest in the same item. You could also offer to take their name and call them if the item is still available when your sale is over. Good luck.
