Would appreciate any suggestions as to where I can find a copy of Harry Potter Book 6 (in English).

There is an English book store section in Gubei Carrefour, near the bicycle/toiletries section. They have Harry Potter for sure and if they don't have it in stock, you can order through which means they bring it in from another branch. There is also Chater House bookstore in Superbrand Mall, Pudong as well as Times Square in Puxi.

The Chinese book stores in Fuzhou Rd also carry it in their international section.

OK, thanks!

there is also one bookstore at the corner of shanxi lu changle lu where i bought my book 7 from JKR. also found some half-blood prince copies.

Foreign Book Store or Shanghai Book City both on Fuzhou Lu should have it.

the tricycle sellers usually have the whole set if located in expat type areas like Jing An, Pudong LJZ, Hong Mei area, Gubei Area and such... aorund 11-20rmb a book for those i think

I've never seen any tricycle sellers in the Hongqiao area. When do they usually come out?

umm...my buddy sent me an e-book version.
I can give you if you wish.
