The marginal cost to produce the few milligrams of the drug that goes into the pens is much much less than $2.83; it's on the order of cents. Plus, scaling up manufacturing of the drug is easier than scaling up manufacturing of the auto-injectors (which have a decent number of parts in them). The auto-injectors really are the bottleneck, and manufacturing of them so far has not been able to be ramped up quickly enough.
