Within the past year Ebay has started deleting teacher manuals for sale, they say they are to be used for teachers only. Seeing that I believe we are teachers, I started searching for other websites that allow it.
Here are a few that I have found:

http://vegsource.com/homeschool/
http://charlotte.craigslist.org/
This website below is one of most favorite websites. Not only does it have the curriculum, it has a chat that are only homeschool moms, and it is a wonderful mentoring site, and is a great place to get answers.
