MDinana - You need to add to your store some kind of fire-making and cooking supplies. Firesteels. Packaged tinders. Alcohol burners. Tarps. Maybe inexpensive tents. Paracord. Whistles. Signal mirrors. Emergency bivvy bag (like the AMK HeatSheets ones). Water purification tablets, filters, etc. A handful of decent survival books.

I would certainly patronize a well done store like this. Much of the stuff you would want available at one location. Not massively overpriced.

I don't think a local mall store would do well in the long term though. Not enough customer traffic after the initial wave of folks concerned about being prepared.
