You can post 100% free on our site, but for those wanting top exposure for their ads we do offer two premium options :
Featured 30 and Featured 60  

Featured 30 - your ad will be displayed for 30 days at the top of our home page in the "Featured Ads" section as well as at the top of your chosen "Category" page and search results.

Featured 60 - your ad will be displayed for 60 days at the top of our home page in the "Featured Ads" section as well as at the top of your chosen "Category" page and search results. 

All featured ads will display the "Featured" ribbon as well as a highlighted background and a border, attracting much more attention then regular ads.

The "Featured" option is available at the bottom of the posting page as seen below.
