So I buy organic milk and eggs. I'm generally skeptical of organic stuff, I don't think the label means a whole lot. However, for some reason organic milk and eggs don't go bad for like a month and a half. It's crazy. Now some people may be like: "So what, I always use the milk and eggs before they're bad". Well, in that case, good for you, buy the cheapest milk you can find, however I use very little milk. It's a total waste for me to buy conventional milk, it always goes bad before I've had half of it. Eggs I can sometimes get away with, but sometimes I don't feel like eating a bunch of eggs, so organics give me a nice little time buffer.
I'm convinced I save money by buying organic milk and eggs. But I haven't run the budget. I'm too damn lazy.
