So I suggest that I get 3 food, 1 firewood and 2 water. Does that work for you?
No it does not.  I'd like to do a proper negotiation.
Well I am a diabetic so I need lots of food to keep my sugar levels up, everything else we can negotiate on.
I can do 2 packages of food.  I would want 3 packages of Firewood.  We can negotiate the water.
I'll need firewood as well since being a diabetic makes me pretty cold at times. So how about I get 2 food, 1 firewood and 1 water?
No how about 2 packages of food, 1 package of Firewood and 2 packages of water.
Is that suggestions for you or me?
For you.  I'd give YOU 2 packages of food, 1 package of Firewood, and 2 packages of water.
Ok great, you got a deal!
Ok sounds good.
