Flight

How can i get the prices to one way trip from Shanghai to Hong Kong between these dates : 6th June to 12th June? (Looks like your site has the best deals but i can't find any price for this flight)

When is the best time to buy domestic plane tickets and is it more convenient for me to buy them on the spot in China? (I will buy few tickets - end of May and in June)

Thank you in advance :)
