After watching the two videos answer the following questions

1) Why does TRUVADA cost $1,780 in the United States whereas it's just $8 in Australia?

2) Can you provide other examples of price discrimination? Please explain how price elasticity of demand determines the difference in prices across consumer segments in your example.
