I think the asia edition should be very similar to the US edition.
I studied Accounting in Hong Kong ten years ago, and the Cost Accounting
book in Asia version was priced a little bit over HKD 200. And i compared
the same book in the U.S. univesity bookstore, the US edition was very
similar to the asia edition, e.g. the same publisher, author and material (
hard cover with colorful pages) and it was $120 in USD (5 times more). Some
of my cousins want to save money by buying the books from HK and take it to
the US back then.
