Seller: Hello
Buyer: Hi, I am interested in buying your digital answering machine. Can you give me more details?
Seller: Yes, absolutely! This is a very fine piece. In 2017 one of this biggest problems is that people can't leave voice messages on your land line. This bad boy solves all of that. It not only records the message, it also notes the date and time. It can even be mounted on the wall with velcro or used as a target for your shotgun!

Seller: Sorry, but I think the lowest I could go is $15
Buyer: Okay $15 sounds good to me.
Seller: Alright, if you're going to pull my leg, I can do $14.
