Thousands of U.K. copies of Jonathan Franzen's Freedom (which GOOD is reading for our first ever book club) were mistakenly printed and sold with an early draft of the book, which includes spelling and grammatical errors and versions of characters that were changed in the final draft.
HarperCollins is of course allowing customers to exchange their faulty copies for new ones. I'll leave it to you to make the requisite "corrections" jokes in the comments.
