This is bogus. Wal-mart sells insulin for $24.88 a vial without prescription currently. It's only the newer 'guchi' insulin brands that are crazy expensive. Stuff from 1996 that is compared to in this article is actually cheaper than it was in 1996 (adjusted for inflation).
It's likely not what your doctor prescribed, it doesn't last as long, it requires you (or your young children) to eat on a very specific schedule, it can't be used with an insulin pen or insulin pump, it's just all around a worse and less effective treatment.
