Yeah actually.. when things are on sale I buy in bulk like a hoarding mother.
I have 'cases' (if you want to call them cases) of extra toilet paper, and extra bottles of detergent. Extra bottles of dish soap, shampoo, canned food in case of anything too. Extra razors. I have extra tissues and I'm actually running low on my stock of paper towels so I'll need to buy more of that. I have extra salad dressing in the cupboards, and some condiments too. I do a once over those every couple months to make sure I use them up before their expiry date :3 I keep extra tape and always pens and pencils on-hand.
I'm well prepared for a zombie apocalypse >:3
