This is the listing I used when I purchased it in 2013 (the price and quality were fine for me, I'd probably buy this again if I wanted to experiment more).

Granted, I'm a geologist that works in the metal's mining industry, so my idea of what is "cheap" for a metal ingot might be a little skewed, as I'm comparing it to the prices of other metal ingots like platinum, silver, zinc, etc.
How about Amazon you pansy.
It's available on amazon. I'm all over it.
Amazon
I bought it in preparation for an experiment that I was going to run on making some very large lab-grown samples of my own.
This site says it's about as common as silver. Here's a chart that seems to confirm. (Ag-silver, Au-gold, Bi-bismuth) You can definitely make your own bismuth crystals at home, and can buy it from amazon.(not a referral link)
This guy is right.
Do this outside. Maybe set up a fan blowing this shit away from you.

A cursory search says muriatic acid from the store is around 10M which is dangerous. Skin burns would suck, but accidentally inhaling a bit too much of the fumes will burn your lungs and send you to the hospital.
Dilute the stuff down before use. Use a glass beer bottle since hydrochloric acid seems to attack a variety of plastics. Measure out nine parts of water then add one part acid to it. Measure out water. Add acid. ORDER MATTERS. If you do this in the opposite order, the acid could boil and splash.
In my opinion, you guys should just source the bismuth from an online supply store. That acid is dangerous shit. (http://www.amazon.com/gp/aw/d/B001QUVMC8/ref=pd_aw_sims_2?pi=AC_SX230_QL60)

Besides fix as many world problems fixable by money (hunger, shelter, health) as possible, which I don't think is what you are asking about...
you can buy a pound of bismuth on for 20 bucks and make dozens and dozens of your own on a kitchen stove. You can google up directions, but a basic summary. 1) melt all your bismuth in one container, pour into a second (leave the silvery oxidized film behind) 2)cool as slowly as possible 3) as it begins to turn solid again pour off the liquid, leaving crystals formed around your container.
