I receive a free homeschool radio show each week from www.HomeschoolRadioShows.com, which is a super site. Anyway, they've JUST last week started yet another "freebie" thing, this time it's a free homeschooling resource (ebook) each week. The website is called www.homeschoolfreebieoftheday.com and they've got great things. Last week, being their kick-off week, they had something every day.
If you sign up for either of their sites, they send NO spam or commercials or anything except their once a week announcement of their program (or ebook) for the week.
