I was about to come in with some dumb answer about expected value, but I actually think this is a neat idea.
I often worry (not a lot) about letting my family down being unprepared should there be some real bad disaster, and so I would be interested in a couple of packages like below:
* Holiday first aid and disaster kit and training
My son recently cut his chin open in Greece and I realised I knew nothing about stitches, keeping them dry, had not got steri strips or bandages. Most people would pay decent cash for a holiday specific package (going to this country? You need these injections, got children of three years old - have a selection of these sterile what nots)
Throw in a private YouTube showing how to use them and I would pay up (of course too late now but that's the market to go for :-) maybe insurance companies sell my data?)
* the civilisation collapses at home package - I don't have enough tinned goods and stuff to last. Not do I have enough water or first aid. Sell me big box to go in the garage that lasts three months (which is what I think you are doing) and I might be interested.
* sell me some sensible prep - like where to meet if the local oil refinery catches fire and we cannot get to our house, evacuation kits that are stored at some place sensible. Seems a bit odd
I like the idea of being prepared - and would pay for a book to tell me how, and a weekend to do it. Being prepared on holiday is a much more realistic market and I think worth investigating - but as for zombie apocalypse - nice selling point, but I think it's going to be a loss leader to establish credibility
