Hello how may I help you? I'd like to order a new set of sharpie markers please Certainly, I can help you with that request. I see two places to buy a set of markers The cheapest is Walmart Great, how much are they? The markers are $19.99 Ok, add them to my cart please. Certainly. Are you interested in ordering anything else? No that's it. I'd like to apply coupon code ABC123 to my order. Okay, let me look this up. Unfortunately, coupon ABC123 is expired. I'm sorry Oh well, worth a try. I'll still check out. Great! Starting your order. Thanks!
