Wow, I would get paperback faced with that difference, no question! There is no shame in saving money, ever...
Here it was I think $12 more in total at Amazon....$16 paperback & free shipping if I ordered other stuff ($25 worth total), or $22 or so plus $4 shipping (regardless) for hardcover. With tax about $30.
I went for it because I thought of my cookbooks and some gardening books, and the paperbacks have really taken a beating over the years. I can now afford the difference, and I am hoping this book will be a similar reference.
I am an addict. I admit it. And have very little intention of ever giving up my habit.
As to the hardback, I agree completely! If the difference had been anywhere under double I would have gone for it (solely because of the high recommendation). Most of our Fiction collection is Paperbacks now. And we are doubling it up slowly on Kindle and Kobo because of our current living conditions. Once the house is built and I can start putting bookshelves into the library I will be SO happy! We had to make a custody arrangement with our roomate for some of the books when we moved here... “ok, you should take this series and that series, but we will take these two? Ok, how about I throw in this one too? Deal? Deal!” That’s what you get with three voracious readers with similar tastes in the same house for over seven years (the movies were way easier to sort out)

Yes, DH’s LEGO got a good portion of one bookshelf, but we also had them in the dining room, both our bedrooms (nothing like having to raid your roommates dresser for the next book in your series, I’ll just step over this laundry, it’s ok... really), and there were still some boxes of books in the garage storage that we never managed to unpack. The real estate agent strongly suggested we back up all the overflow books prior to the listing. I‘ve given my mother Heck every time she has moved without me for Donating books I didn’t want to part with. Especially the entire Pern series in Hardcover, and some of the sci-fi classics.
