Hey, I would like to have some extra supplies. I am really a coldy cat and could use the extra firewood. How about...I take the extra firewood and 1 extra package of food and water.
Hi! It looks like we're interested in the same supplies. I get really cold being anemic. Would you consider taking one extra firewood, 2 packages of food, and one water?
I am sorry to hear you are anemic. I guess I could make camp with 1 extra bundle of firewood.I am ok with the 2 packages of food but I would like 1 extra water than . I have a weak stomach and need to cook everything in potable water.
I appreciate your willingness to part with the firewood. Why don't we agree to switch the water and food, so that you end up with 1 firewood, 1 food, and 2 water packages?
I really could use the 2 food packages though. I am having a friend coming over to visit. I did not count on him.
If you had to choose only one, would you prefer to have more food packages or water?
Well...since my friend has a healthy appetite 🙂 and has a iron clad stomach, I would prefer the food packages .
OK, I need a few minutes to consider how important these packages are to me. I appreciate how patience and courteous you are being. 
Ok. Take your time. No problem at all.
Alright, if you'd agree to me taking all the firewood, you can have all of the food packages and all of the water
