To everyone saying no purchase took place - explain this!
Sony even tells me to print it and keep in a safe place for future reference! Sounds like at least they think it's an important and binding e-mail. But I guess the part they really want you to agree with is that there's no refunds.
Did you also read the terms of service that they say also apply with the purchase?
