I got this book for $11 and I must say it’s one of the best books I read recently.
If you are from Europe, the US, the UK, or Canada then you can purchase a $7 AppSumo deal and get a book delivered mostly for free.
If you want the Kindle Edition, It’s only working in the US.
Check out this book and get it at $7 – https://appsumo.8odi.net/Jz0bPv
