15 things you can buy from Costco, Amazon, Sam's Club, and BJ's to be ready for when the apocalypse hits

You can't survive long without water. Don't be shy about hoarding all the bulk packs of water bottles and water cooler containers that you can lay your hands on. If you want to really get ahead of the game, you can even collect the supplies you need to make your own water purification system.

Pure honey never goes bad, so you can still embrace your sweet tooth after the arrival of the four horsemen. For $126.99, you can buy a 40-pound tub of US-made organic honey at Costco.

Some eschatological scenarios hold that darkness will envelop the earth during the end times.

So it's important to make sure that you're able to see, whether you're hunkered down in your bunker or attempting to traverse a post-apocalyptic terrain. Glow sticks can help light up your life, literally.

Fortunately, Fire Supply Depot hawks packs of 50 green light sticks that glow up to 12 hours each. If you decide to buy multiple packs, you could save up to 20%.

Salt would be an important commodity in a world without refrigeration, allowing you to preserve other foods. You can buy a 25-pound bag of salt on Amazon for $30.99.

Milk probably shouldn't be at the top of your apocalyptic shopping list. Even if you're able to keep your supply refrigerated, milk only lasts so long before it starts to stink and curdle.

But powdered milk is a different story. Unopened, a 20-pound pail of powdered milk from Target will last up to 20 years. This spotted, four-gallon bucket will set you back $95.33.

If you keep rice dry, it'll last for decades. Amazon sells a 28-pound bucket of white rice, which boasts a 30-year shelf life. Altogether, the pail contains 45,900 calories.

You've got to be on alert during the apocalypse, so don't let the end of the world drive you to drink. Still, whiskey is a good option for anyone who wants to party like it's 1999. As long as you keep the bottle sealed and stored properly, it'll last.

When it comes to buying whiskey in bulk, there's a $167.32 4.5-liter bottle of Jameson up for grabs on the Masters of Malt website. Unfortunately for American preppers, the website also says that it's currently unable to deliver this behemoth beverage across the Atlantic.

Maintaining a sanitary environment in your survival bunker is key. You can purchase a portable toilet on Amazon. If you want to be extra prepared, you can spring for a pack of four mini-toilets for $246.99.

What's harder than making it through doomsday? Making it through doomsday with a baby in tow.

If you suspect that you might become the post-Armageddon caretaker of a small child, it's not a bad idea to drop $407.76 on a 12-month supply of diapers at Sam's Club.

The fall of society is likely to make dashing over to your doctor's office a tad more difficult. A first aid kit, which you can find on Amazon for $25.57, is a must for your survival bunker.

Any smart prepper knows to keep a good amount of apple cider vinegar on hand in case of emergency. Not only can you add a splash of this mild acid to flavor your food, you can also use it to keep your survival bunker clean.

WebstaurantStore.com sells a lot of 48-gallon bottles of the stuff for $367.2 — $7.65 per bottle.

Dry beans have an excellent shelf life, and therefore should be considered key staple of any prepper's grocery list.

You can get a substantial tub of dried pinto beans for $100.98 at Sam's Club.

Ramen isn't just the stereotypical meal of choice for cash-strapped college students. These noodles can last for a decade, making them an excellent option for survivors living during the end times.

Roundeye Supply offers consumers a number of relatively cheap bulk options in a variety of different flavors.

The end of the world doesn't have to mean the end of pancake breakfasts. BJ's sells a 28-pound pail of pancake mix for $61.99. All you need to do is add water to the mixture, then get to flipping.
