Have you heard of Tyndale Rewards? I just learned about it through Money Saving Mom. Basically, by signing up you can earn 25 points and then there are various surveys and things you can do earn points. Once you have a certain number of points (ranges from 30-200 points right now) you can redeem for free books!
You can sign up through my Tyndale Rewards link here and you get 25 points and I get 10 points for everyone that signs up through my link!
I already review books for Tyndale Blog Network and I am excited to participate in Tyndale Rewards, too!
