Just saw this display at a chain bookstore

The picture doesn't really convey how grim it was to be confronted by this irl
If I wrote a self help book, it would say, don’t pay for self help books when you can instead read famous amazing books for free instead.
Someone did sell one like that, a $15 self help book about how to become a millionaire. Then when you opened the book it just said "sell 60,000 books for $15/each"
