I've decided to order Apologia's Exploring Creation with Astronomy for my younger son and Apologia's Exploring Creation with Zoology I for my older son. Do you happen to have a coupon code for Home Science Tools' website? :love:
Don't know of a coupon code, but I have the Astronomy book that I can sell you (cheaper than on line), if you're interested. I used it last year with my dd--she loved it! You can pm me if you're interested.
