Hello how may I help you? I'd like to buy something. What would you like to order? I would like to order this book. I can order that book for you. The price is $13.99. Alright, I have this coupon. Can I use it now? I'm sorry your coupon has expired. Okay, cancel the order for the book then. I will cancel your order. Would you like to order something else? Nope that's it thanks. Thank you.
