If you're at all into gardening,  or any kind of prepping, you NEED this book. 
and for just a couple days it's on sale for only $20. I can not tell you how great a bargain this is.  Over 400 pictures of how to be a better gardener, with just tons and tons of info.  I've had this for about 5 years now and use it every season.
