Essential oils are expensive. Synthetics are cheap…but the real thing is so expensive. I think when I was just buying a few milliliters, I didn’t ever stop to calculate the per oz cost. But, for doing big batches, it’s silly not to buy in bulk. But good lord, there’s some sticker shock…I tell you what. Some of the things I really wanted were more expensive than I could possibly envision buying. For instance, real ylang-ylang extract is almost $150 an ounce…*eeeee!*. So, we won’t be including that particular floral in our recipes any time soon. Yeek! But on the plus side, I’ve started ordering materials. So, yay!
