Yeah Roth, people see a little bottle for $4, but that will last you a long time. I've been through 8 16oz bottles and haven’t hit half way. The amount I use is really a top amount, you can use less, and probably stronger scents even less. Also you can get that little ball from amazon for about $30, no need for the fancy ones; the black one fits my decor anyways. You can also just buy the wick from ebay for $5 delivered and make your own. I'm looking around for something cool to make with the one I got. Another thing is don’t fire the stone, and forget about it lols, and cap it when you’re done, that stone will stay hot for many hours past what you need and keep burning the alcohol until it's gone.
