Hey - while I tell it far and wide in my own community, I don't think I've ever mentioned it here-
Barnes and Noble Bookstores issues home educator cards, did you know that?
All your books for school - for us child-led families, that means everything, I'd say- are 20% off your purchases. Not including text books.
I swear I save at least $5 every time I go.
It's free to get a card, just take in whatever you have that says "I home educate", whether it be membership card, a lesson plans, or whatever you recieve from your state.
I'm sure it's a national policy for them.
