Thank you for contacting Acme.  How may I help you today?
I am thinking of placing an order for a birthday gift, and I wanted to see if the promo code that I have is still good.
Sure I can check on that for you
Thank you
Our promo codes usually expire 7 days after they are issued
Ok, I got mine 3 days ago, so it should be fine then.
Yes, it should be.  Were you having any problems at checkout with your code?
No, I hadn't tried it yet.
Okay, well in looks like you are in good shape, and your code should be good.
Great, thank you!!
Is there anything else I can help you with while we're here?
No that was it.
Okay, have a great day
