Hi! I see you've found my bike
Yeah! I see you're offering it for $50, but I'm wondering if you'd be able to negotiate something a little lower
I'm willing to discuss price within reason
Cool, how does $30 sound?
That's a bit low, I'm pushing for closer to $42
Hmm, would you be willing to go below $40? Maybe $35?
Make it $37 and you've got a deal
Perfect! $37 it is
