Seriously, it's a thing. Sure, it's more of a collection of items thrown together on a page for their supposed utility in surviving hordes of the undead, but hey, who am I to turn my nose up at the opportunity to buy every variety of duct tape that Amazon offers?
As you can see, their categories of offerings stop just shy of presenting actual self-defense items (machetes, clubs, semi-automatic rifles—you know, the basics) for you to purchase, but that doesn't mean that their shopping list is without value — it's just incomplete.
Though really, I've got to question some of their ideas here: Safety goggles? Vests? Helmets? As someone who has spent far too much time absorbing zombie-related material in the past few years (with "Shaun of the Dead" and Max Brooks' "World War Z" in heavy rotation), it's obvious to note that every zombie-preparedness kit must involve gear to protect the extremities from bites and clawing, and vests aren't going to do the trick.
But the interesting thing to note is the tiny logo in the center of the page: a clickable image promoting "Call of Duty: Black Ops 2" and its zombie-survival mode. That can't be a coincidence, right?
At the very least, make sure to check out the selection of zombie-related books, films and games down there at the bottom. Personally, I recommend Colson Whitehead's "Zone One" — it's a captivating, if bleak, look at what it must be like attempting to survive in post-apocalyptic New York as part of a block-sweeping clean-up crew.
