I can't spend anymore money after I buy my English textbook. How much is your English textbook? It's $198. I'm not kidding. That's ridiculously expensive! What's the title of the textbook? It's called How to Write Well. Dude, someone is selling that book for $30. No way. What edition is it? I think it was the 10th edition. Oh, no wonder he or she is selling it for only $30. What edition do you need? I need the 21st edition. The publisher seems to be really making money, considering the number of editions.
