Hello! Are you interested in the lamp?
I am. Does it still have full range of motion?
Yes it's only been used a couple times and is in near brand new condition!
Great! I noticed that you have it priced at $75, I was wondering however, would you be willing to come down a little? 
I could possibly, How much lower did you have in mind? I would like to stay in the 60-70 area if possible though.
Oh man. I am just a struggling student and this would be perfect for my dorm room! What If I met you half way at $35? Not trying to insult you, but funds are limited these days.
How about this? I'll throw in a 12 pack of light bulbs, and bring it to you for $50? I'm getting ready to move and could really use any money I could get to pay the moving company.
I can totally swing $50 after tomorrow night. Will that work?
