Helium previously costs about $8/liter but is now running about
$20/liter thanks to the helium shortage. That's $14,600 for 730

Hmmm... that can't be right. The problem is that I'm getting prices
for helium that are all over the map. For example:
http://www.reuters.com/article/2013/09/19/us-helium-shortage-analysis-idUSBRE98I0AN20130919
"... spot price of liquid helium has jumped to $25-$30 per
liter from $8 last year."

http://www.crainsnewyork.com/article/20140126/FINANCE/301269974/helium-shortage-deflates-party-city
"prices have doubled since 2006, to $6.13 per-cubic meter,
according to the latest figures from the U.S. Geological Survey."
1 cubic-meter = 1000 liters, so that is $0.00613/liter which seems
rather low.

http://minerals.usgs.gov/minerals/pubs/commodity/helium/mcs-2014-heliu.pdf
"The estimated price range for private industry’s Grade-A gaseous
helium was about $7.21 per cubic meter ($200 per thousand cubic
feet), with some producers posting surcharges to this price.
1 cubic-meter = 1000 liters, so that is $0.00721/liter, which agrees
with the previous article, mostly because the price came from the same
source.

Ok, let's try party helium:
http://www.sfparty.com/products.php?product=Helium%3A-Balloon-Time-Disposable-Helium-Tank-Purchase
$55 for 14.9 cubic-ft.
14.9 ft^3 = 422 liters
$55 / 422 liters = $0.13/liter

Does anyone have the real price of helium?
