The one the article is talking about unveiling is the new style ($86 at Walmart). (The old style can already be found at Walmart for $25.)

Walmart sucks in a lot of ways, but this article does not demonstrate that.

> Because this old style insulin acts slower than the more modern version and requires a rigid eating schedule.

Good thing the article is about Walmart now selling 'analog insulin' ie. modern version of insulin

The article says that this is one of the newer ones distinct from the formulation they already sell.
