This is just a thought, I could be wrong. Parrifin does cost more but isn't it easier to wick, to color and less picky about f/o's that are compatable? Soy is some what harder to find f/o's that will throw, not to mention can be a pain to color. Think about how much $ goes into testing supplies and pain relievers. Just a headache to work with some times. Just in my area, pure soy candles are rare and hard to find. So just like any rare and hard to find artifact, it's more pricey. If people really want a soy candle, they need to pay for my headaches, lol. I could be wrong. :undecided
