How much did you pay last time you bought a book?
Books are expensive!
And doesn’t it seem like every time you go to buy a new book, the prices have gone up?
You’re not imagining it!
Just like college text books, book prices have been going up steadily for the past few decades, maybe not as much as college text books have (a whopping 1041% price increase since 1977!) but they have been going up.
And if you’re a bookworm, buying a few books a month can put a serious dent in your budget.
