Buyer: Hello. 
Seller: Hello, Thank you for contacting me, As you can see the bike is in pretty good condition, there are a few after market parts I have added, and I will be throwing in a free bike lock.

Seller: You know what? Id be more then happy to do that for you. Thank you so much for such a simple sales process, Id be more then glad to see someone else get some use out of the thing.

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!
Buyer: Haha. Would you be willing to take $16 for it?
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.
