Four stars alone for this store actually existing in real life. I am truly impressed that some amazing person's time and money was put into creating a store dedicated to a (potentially) impossible threat.
As for the goods, there are plenty of zombie items but also a lot of stuff that will keep you alive once Vegas implodes.
If anything, go to store just to say you've gone. And while you're there, pick up a poster, sticker or machete to support this ridiculous business endeavor.
