Query: I was disappointed

I was very excited when I bought the Kindle, it was an e-reader I wanted to buy for a long time.But ... when I received the Kindle and thought I could buy a lot of cheap e-books I was very very disappointed. Why? Because as a non-US citizen I have to pay a much higher price for e-books than Americans!!! Why didn't Amazon warn me beforehand about this???? I could have bought a European e-reader and would still have to buy higher priced e-books. For that I don't need the Kindle.Shame on you Amazon. So non-US citizens, don't make the same mistake I made.
