Can I buy train tickets at Pudong airport?

I am arriving at Pudong airport on 26th October 2011 at around 15:30, and need to get to Hangzhou. I am thinking of taking the metro to Hongqiao station and then taking a train from there to Hangzhou. I heard that the tickets for bullet trains are in high demand and they are often sold out so it’s best to buy them in advance. Can I buy tickets at Pudong airport? I don't think I can use the ordering service on this site because I don't have an address in China for the tickets to be sent to.
