Hello
Hi There!
Do you fancy this item I am parting with?
Yes.. Does it work for any type of Iphone?
Yes, it works with iPhone and iPod and iPad. 
How is the audio?
It's excellent. It is like new. You are getting a great item here.
Oh great! Will you accept $28?
I'd like 35. Is that okay with you?
How about $30 and I can pick it up. So you don't need to ship it
That works for me. 30 it will be.
Thanks
