Hello how may I help you? Hi there! I need to buy something. What do you need to buy? I need to buy a pair of socks. What color socks? They are purple and black. We have those for $2 a pair! Great. I also have a coupon. Can I use it? What is the coupon number? 999000123. Unfortunately that coupon is for yogurt, not socks. Darn. Okay, just order the socks then. Thank you! You're welcome
