I stopped using "regular" scented candles for these reasons: they contain paraffin, a petroleum by product. Not earth friendly and possibly unhealthy when burned. Soy candles burn longer, cleaner and are made from a renewable resource.
I was recently at a Yankee Candle store and a really nice sales person saw me looking at the Beanswax candles. She was very nice in explaining all the scents. To be honest, though, I wasn't too impressed with the scents. Don't get me wrong, they weren't bad, just kind of...there...and not very strong.
They also were a little expensive. The 18 oz jar cost $24.99 plus shipping. I've been buying my soy candles from Swan Creek Candle and their most expensive candle is $19.30 for 24 oz. Plus they send one free candle (usually 6-7 oz) with each order. I love their scents...especially the Thai Pear (and, no, I'm not on the Swan Creek payroll- I just LOVE their candles).
So I applaud Yankee for getting with the "green" program, but the cheap side of me will stay with the Swan Creek candles.
P.S. For those of you who read the "I'm scared of my compost bin" entry...I survived!!! It wasn't bad at all :)
