The Frugality of Soy Milk
Recently (as in the past three months) I’ve begun using soy milk. This is quite a change for me, as previously I would turn my nose up at anything other than whole milk. And I admit that I still don’t like the taste of soy milk nearly as much, but it isn’t something I actively dislike.
Why the switch? Well, there are a couple of reasons.
1. Health
Young has been trying to gradually wean me off of my high fat, high meat, high salt diet. (And she’s mostly succeeded.) This is merely one more step in the program. 
The interesting thing is that even though I still prefer whole milk, the more soy I drink, the more I like it.
2. Frugality
Surprisingly, despite the fact that soy milk is more expensive, it turns out to be the cheaper option for me.
My problem was that though I preferred whole milk, I didn’t actually use it all that often. At most, I’d have two bowls of cereal a week, and I rarely cooked with it. As a consequence, the milk would always spoil before I’d manged to use even half of it. But soy milk can last a very long time. In fact, since I’ve switched to soy, I haven’t had a single spoiled container.
I estimate that I save at least $2 each time I buy soy.
Are there any “expensive” items you buy which actually end up saving money?
