How can some places sell pillars at the really low prices I sometimes see? The prices are great but it makes me suspicious.

You are right to be suspicious. Remember the old saying about "too good to be true', it applies in all things. When you see really inexpensive pillars, there are generally one of 2 reasons. A) It is being sold at a loss to get you to try the product. Or it really is a cheaply made product. This actually works for almost anything. I learned it the hard way in my younger years. Things to look for on the web or at the store. bad words: "overdipped" usually means a plain unscented candle that has been dipped in scented wax of the appropriate color. The base candle that has been dipped is usually a "pressed" candle. This is method of mass production where wax beads get dumped into a mold and then a piston presses the wax into the mold, the candle is then drilled to place the wick and then the candle gets dipped a few times in the scented and colored wax. Easily identified by weight. When you pick them up they do not feel as heavy as you think they should be and they are not. This is because the pressing process only uses enough pressure to get the granulated wax to stick together, it does not remove all the air. The granulated wax is rarely scented although the overdip wax is and some of the scent will transfer to the center. To see this for yourself buy one of those dirt cheap 3x6 candles at your local discount department store and cut it open with a large knife, you will see what i mean. "lightly scented" usual translation: "we went cheap on the scent load" or it is an overdip Note: All of our pillars are fully liquid when poured into the mold. Scent and color through and through, and then air cooled for 12 hours before being released from the mold. This makes them much heavier than you would expect and gives you what you pay for.
