What if the person has no online business??

I am confused about how to enter a URL when setting up my account to
post items in Froogle. I do not have an online store from where I can
post a URL. So how can I go about creating the URL that your site
requires? I have several friends at work who are trying to do the same
but have the same questions about the URL factor. Please let me know
when time allows for you.
Many thanks!!
