Yup. I just use whatever cheap jars I can find (like I can get 3 or 4 8oz tumblers in a pack for 99 cents).

I don't buy the best wax but I've never had that many complaints. Jar wax is expensive while mold candle is cheaper. I usually mix a little together.

I mostly use wax covered wicks as they stand up and you don't have to have something to wrap the wick around. I tend to buy the long wicks and then just cut them and half and add the bottom. It's not that much cheaper but it's cheaper.

Liquid scents work so much better than block scents and I always add way more than what they tell me so it has a much better throw.
This is where I get my scents: http://www.wholesalesuppliesplus.com/ and sometimes color.

The wax and wicks I buy at Michaels.
