Hello! I am really interested in that phone you have for sell! 
Thats great! Its a really nice Samsung Galaxy @7
I am still sporting an old T9 phone and everyone keeps making fun of me. So I think it's time I step up my smartphone game. I did some reasearch and this phone looks like it may suit my needs. You say there is a cosmetic issue can you elaborate on this?
Just a small mark on the top right corner. It will not effect the usability of the phone, but it is slightly noticable.
I'm really girlie so things like kind of bother me. Can we negoiate the price a little seeing how it does have a cosmetic look and this will be my first smart phone ever?
Its lited at 350. I an  go to 320
Hrm I am a little tight on cash right now. What about 250?
280 and its a deal!
