Hey Susan, are you interested in buying some used books for school? You can really save some money that way.
Well, what do you have?
Well, let's see. I have a science book called Today's World and I am selling it for 30 dollars.
30. That's too expensive for a broken book like that.
Maybe so, but I bought it for 60 and I wrote a lot of notes in the book that should help you with the class if you could read my writing.
What else are you selling?
OK, I have an English writing textbook for 14 dollars, a math book for 23 and a novel for only 7.
Hmm...
It's up to you. You know these things go fast.
OK, I'll take the writing book and the novel. I need both of those for sure.
No more textbooks?
Not now. Teachers are always changing their minds about textbooks.
