Comfrey book

I have been looking for a copy of Lawrence D Hills book 'Comfrey: Fodder , Food and Remedy'.  I cannot find a copy under 120 pounds and one offer was for over 7000.  Either Comfrey is more amazing than I thought or this book is so rare it is only available as a collectors item.  Any thoughts?

35 pounds is the cheapest that I could find.

Thank you Bob! Still 15% of my monthly pension though.

Just had a quick look and it's out of stock. But thanks again for finding it. I'll put a watch on and maybe there'll be another.

Both of Lawrence Hill's comfrey books have wound up on the list of digital downloads that you can get from
the    soilandhealth.org.au   because of their being out of print for so long.

Looked up the Canadian Amazon---hardcover is 439.53$Can or 50.85 for softcover--expensive books....
If you just want them to read, they can be downloaded from Soil+Health for free; you just have to
say that these digital repros are for your personal use and not for resale.

Thank yoy K Jay. Have ordered both. What an amazing resource!
