If the world is going to come to an end and you need supplies I rather be stranded in this store. You will have but not limited to dried food rations, purified water solution, knives, motored flashlight, flares, and backpacks to jammed them all in. Better to own the place because you will be prepared for a disaster and its not only just Zombies!
I would definitely come back. I may want to get the target zombie wallpaper so I can bring to the archery range.
