how we doing today partner
I am doing fine. Is this bike still available? I need it for my son who is going on a moutain bike trip. are you able to negotiate on the price?
that perfect, yes I can slightly negotiate 
I am not sure how often we will use this bike afterwards so lets make it a cool hundred and it will be a deal.
thats too low for me, but I could let it go for a cool 130 and you have to pick it up here, is that fair enough
do i least get any gear with that? Lets do $115 I pick it up within the next hour.
ok let me settle for 120
Actually I just counted all my cash here and i need to put gas to get the bike can we do 114
