You’ve known the book’s condition via chat (it’s highlighted) I told you the book was all good before our trade. But as the day we met was raining heavily, it got soaked with some water so I also lowered the offering price (which was already extremely low). Plus we met face to face. You have examined the book thoroughly and physically. You even called your son to ask if it was okay. He agreed so you agreed the trade. Therefore, I really don’t understand why you would have posted this comment.
