Sometimes you can buy 100% beeswax candles at health food stores or at craft bazaars. You can find lots of different places to order them online, but they are going to be pricey. I was looking for a Trad Catholic convent or monastery that was making them, but it seems they are busy making coffee, fudge, and bread... so I ended up ordering from an Orthodox monastery. If you do, remember that orthodox candles are smaller in circuмference than regular tapers, so you may need new candle-holders too.
