Hey there, I'm interested in the shelf.  I'm on a bit of a tight budget, would you be willing to drop the price?
hi, it's a nice shelf, decent condition.. how about 60?
Your list price is $50, I was thinking $30
30 is too low... i think 50 is a fair price.. it's not big bucks
Let's meet in the middle, $40 seems fair, no?
it's ikea... let's do 45, i will drop it off
