Lye and Glycerin
If you're in a large enough city, or close to one, you can go to your local hardware store (like Ace Hardware) to get lye crystals. I searched everywhere as well and ended up stumbling on a brand of lye at Ace Hardware for under $4.
As for the glycerine, the only place that I've seen it is at my local arts and crafts store (Michael's), but I only saw the hard block of glycerin. But I did stumble across a block of beeswax over there as well. But I'm not sure if these arts and craft store carry liquid glycerin though, I didn't ask when I was there. So you may want to find out the next time you go to one.
