Hello
Hello, are you interested in the bike?
Yes I am. How much are you selling it for?
I'm asking $340 for it. It is a great shape and has some really nice customizations.
Can I stop by and have a look at it? 
Yeah that's a good idea
Can you lower the price for it a bit for me?
I don't know that is why I put in the ad about lowball offers. It is really priced very well and comes with a lot of great customizations and Kryptonite U lock, Pedro's Trixie Tool...
Okay, how about I pay full price then to make it all right for you?
That would be great I even have a brand new helmet I can give you, it is the wrong color for my new bike.
