There was another thread saying it’s in 30 packs of single use vials for $300.  At that price, I predict they’ll stop making this in a few years. 
You get $40 from a vision plan for an exam, you’re going to spend $10 plus shipping on a 
dilation reversal drop?  Or maybe be you try to pass the cost on to the patient, charge them $20.  Is that even allowed under a vision plan?  Or Medicare?
Drugs have gotten so expensive, there’s almost no point to developing new ones anymore.
