Today I went to the post office to mail three envelopes to my brother. I found out that it would cost me over nine dollars to mail them separately, and the lady helping me advised me to just get it mailed in one package since they were all going to the same address. The total came to $4.05. What savings! If the post office were privately run, they would have an incentive to maximize profits, but since it's run by the government, I'm looked after as a consumer.
