I found this today on Expo in a thread worth reading about non refrigerated food

If I am lucky I can end up with a few left overs ketchup packets from fast food places, but this place sells all of that and more. Things like the single use sunscreen packets that I always feel guilty about taking from work for my first aid kit.

Its not cheap since you can obviously buy a bottle of mustard cheaper then a handful of packets, but its all things that require no refrigeration and take up less space.
