I have a found a site that might help you out during this downturn in the economy. I might be using it since I may qualify for the "moms going back to school" money that Obama set aside ??!!

You can rent your textbooks and it could save you many dollars. Check it out and see if it fits your pocketbook. I will definitely consider it when and if I get to return to school and need some textbooks.
I hope any that desire can attend college and get that degree that could open doors for you to earn your way in the world.
