Buyer: Hello. I am interested in your Tile Mate Item tracker. Will you sell it for $8?
Seller: I'm sorry I paid $50 for it, so $20 seems very reasonable to me.  I will go a bit lower.  Can you pay $18?
Buyer: The max I can offer you is $10. I cannot go higher than that.
Seller: I really cannot go lower than $15.  I can take $15 plus something else you can give me to sell.  Do you have anything to give?
