FDA pharmacy crackdown

You can get the same medicine from the same manufacturer in the same packaging at international websites for 20% of the cost that you would pay in the US.  So the FDA has finally decided to crack down on online pharmacies. This was inevitable, given that the pharmaceutical industry spends more than any other industry on lobbying. They tell us they are trying to protect the consumer, not gouge them. Do they expect us to believe that 80% of the cost of US medicine goes to quality control?
