Coffee will make a good barter item too.
Be sure to get coffee that is in metal cans, not plastic. It will last a lot longer in metal cans and stay much fresher.
I would add salt to your list.
Tobacco is urgent with the new tax of $24 per lb. coming April 1st. I'm only paying about $18 p. lb. now. I have several pounds now but I'd like to get as far ahead of that commie 0bammie tax as I can. Tobacco seeds too. More good barter items.
