Well ... Two ways.
1) Buy used. Half Price Books is a regular haunt of ours. Also, half.com is a great online resource
2) Buy a Kindle. This electronic reader allows you to buy the book in digital format!
As many of you have heard, Blogmania is in full-effect and Bitten by Books is giving away a Kindle!
Wow. How I would love one of these!
Go and check it out yourself!!!
