That's probably true. I remember back in 2009, I was working with a local pharmacist and he hated ePrescriptions. There are a lot of errors and inconsistent coding across EHR's means they have to retype them all anyways. They used to pay 30 cents per ePrescription. If you make a mistake and have to resend it, they had to pay again. They loved faxes though. Those are free.
CVS filled 1.2 billion prescriptions last year. If they paid 30 cents for half of those prescriptions, that would've cost them 180 million.
