Rent homeschooling books...
I ran across this site on another homeschooling site.
They have MOH, Shurley English, Saxon Math, Exploring Creation Science and many more titles.
You rent the books for a 9 month period. Its looks pretty cool.
Use it up, wear it out, make do or do without!!
Do not overrate what you have received, nor envy others. He who envies others does not obtain peace of mind.
