One of the best discoveries I've made in the last few years is the service that our county library offers called
Books by Mail.
This service allows us to order books online and have them delivered to our door within a few days, absolutely free of charge! It's like Christmas here at least once a week. My lil' guy's face lights up when he sees that bright yellow envelope in our mailbox. He'll sit down and read for hours when he gets a new allotment. Not only can you order books, but music C/D's, movies, and books on tape as well. The bonus is that you get to keep the materials an extra week. I hope you'll look into this possibility in your area. The folks at the library told us they encourage people to use the service so that the grant used to pay for it will be renewed.
Another way to simplify.
