You will see affiliate ads, like the EBAY ad below, throughout your site. These are for sample purposes. You can easily replace these ads, and add your own block ads, by going to www.cj.com and joining Commissions Junction. They will furnish all of the ads for you, and YOU will receive commissions off of any sales from your site. If you need help, just email firstname.lastname@example.org .
You can remove this block by going to "Blocks" in your administration panel, and deleting "Affiliate Ads"
