A Title Much Cooler Than Anything on the Old Site
You don't need toilet paper. You would have to amass huge amounts of it to last long and that's only useful if you are bunkered down and don't need to be mobile.Besides the obvious guns, medical supplies, food. What are the things you think you'll need to survive. I think toilet paper would be a good thing to hoard. A few extra pairs of shoes. A couple in my current size, and a couple in a narrower size as my feet may shrink a little. I have super wide feet. A dictionary and math text books. Coffee could be a useful trading item.
A large portion of the world's population does just fine without toilet paper.
Really what you need first is access to water for drinking and cleaning and food. And you need other people.
After that my greatest concern would be access to first aid and medical supplies and hopefully some doctors will have survived.
Also, knives. That really stuck out as a gap in your initial list.
