So I test it out by purchasing books that are not available in dangdang's Beijing warehouse (for international shipment) but are available in their Shanghai warehouse (65daigou's warehouse is in Shanghai).
All in all, 10 books were ordered but they only managed to ordered 8 as 2 of them were out of stock by the time there place their order (according to their website they will place order 24-48hrs after payment received).
Utilising their air shipment, I am happy to report that I got my books after 11 days! I feel the shipment charge is fair but may not apply in every situation (as they charge by weight whereas dangdang charge by 50% of original book retail cost).
So do your math and consider other sources before you jump right into them.
There also other considerations like location of collection, or if you want to pay extra for local (Singapore) delivery. If the books (especially book set) are heavy, cheaper source locally, etc..you can read more about my experience in my blog.
