Craigslist is a free service and it is very easy to use. This link will take you to a state by state listing: http://www.craigslist.org/about/sites Once you get to the area that you want to sell in you click on it and it will take you to a page where you will see what you can do on craigslist. There is a for sale section and you can choose what you want to sell. Once you get into that area you fill out the form and post your ad.This is an example:
south florida craigslist >
for sale / wanted > category for sale
baby & kid stuff This would be the item for sale
