Also, if you have plans for a garage sale, auction, or yard sale, announce the sale on Free4AllCity.com Free Classifieds giving a list of the major items you are selling,  include a picture of some of those items,  and include clear directions for finding your sale.  Then email the URL of the announcement to everyone you know, and post it on as many internet bulletin boards as you can find.  Print copies of the announcement and post them in the local Meijers or other merchant.
