Wondering how it works? Go to the website and sign up! It's as easy as that. Every Monday, you'll get an email letting you know what freebies are available in the week to come. If you're interested, go to the site on that day and click on the offer and get your free resource (ebooks, activity books, etc). You can pass on the ones you don't want. I've found some great newsletters and such, too, by going to other sites belonging to the sponsors.
What are these "freebies?" They're unit studies, curriculum, lesson plans, eBooks, and such. There would normally be a charge, but on Homeschool Freebie of the Day site they are totally free...but just for the one day they're offered!
I've started collecting stuff, even though Delilah is way too young to start, but I like to be prepared. I've got eBooks on English and Grammar, Math, Classic Literature, Greek, and much more. All free.
