Hello, I am interested in the phone. How about $300?
This is a brand new iphone 7 that is factory unlocked.  The factory seal is still on.  I can go as low as $500 for this phone.
Is it the latest model?  
not sure if they came out with iphone 8 or not.  But this one has quite a bit of memory on it.
How about $450? Then I won't feel bad if it isn't.
fair enough.  $450 go ahead and submit the offer
