I started doing research and found some great resources to get free or very inexpensive reading material to entertain my brain.
Everyone knows about the advantages of visiting the library so I will leave that opportunity out.
Free Online Libraries
One of my Christmas presents this past Christmas was a wonderful Amazon Kindle, so I'm all about the free ebooks!
Free Ebooks On Amazon
Book Exchange Sites
(This one costs $2.97 to recieve a book for shipping purposes)
(You can find more than just books to swap here)
Other Places I Suggest Looking
Clearance Racks at Discount Book Stores
(sometimes they sell used books for very cheap)
(Some Hy'vees have been selling used books on a separate rack for charities.)
You could also exchange books with friends or start a book exchange club in your neighborhood!
Don't forget blogs are another way to entertain your mind for free!
