Hi, I'm interested in the IKEA chest.  How much are you looking to sell it for?
I am selling it for $35.  I paid about $100 for it new.  It's in great condition.  Do we have a deal for $35?
How about if I take it away for you, since you're moving, for $20.  Deal?
I really need at least $30 so I can make it worth my while.  Deal?
Can you throw in the flowers pictured and the balloons for $25?
If you can pay $30, I will throw all of that in.  Deal?
