Hi, are you interested in my dope bike?
Hello, I may be interested in your BMX bike you have for sale. 
Its an awesome bike, what is your offer
Considering it needs a new chain and the brake cable is missing, I think $60 is a fair offer. 
If you throw in something else to sweeten the deal, im in.
I dont know what I could throw in, its going to be for my son and I would have to still take the bike to have a chain and cable put on so he could ride it. 
Do you have any old Hoobastank CDs? I'm a collector
No, I am not in for trades, I can do cash only. 
The only way im going below $90 is with a trade added in. My asking price is $90 and i could buy at least 45 hoobastank CDs with that amount
Ok, well I see another bike in better condition for cheaper so I will go with the other. thanks for your time.
