I hope you and your party are as excited about this trip, but we need to figure out how to share these supplies! 
Are you looking for any specific items?
Well, we will be near Mt. Getscoldthere and I know it's supposed to be unseasonably cold.  We are definitely in need of the firewood. 🙂
I'm traveling with a large family and kids love to sit next to campfire at night.
We have a party of 10 and one of them is anemic, whose condition is really exacerbated in the cold.  The other thing we are in pretty desperate need is water.  Thankfully, we are pretty good on food overall.
In that case I would love to keep all of the food. 
I think we can definitely consider that.  It's just a matter of hashing out the details on the other two items.
How about I get one wood, three food, and 1 water and you keep the rest.
I think that could work.  It's a little less firewood than I was hoping, but I think we can get creative with how we use it.
Perfect, let's do a deal.
