The new Harry Potter book is $225 HKD in Dymocks. They are having a laugh. $180 over in the shop in Tower 1 Exchange Sq. $163 online at Paddyfield, or around $120 from Amazon, plus delivery though.
Free, on the internets:
the complete e-book has been fully scanned + proofread, in about 12 hours after the hardcover book had hit the stores.

$180 at Page One, Kelly & Walsh & Bookazine as well
I got mine for $157 in Dymocks by ordering it a little while before.
Rowling, the author, made US$ 36 million the day of publication. They expect this one to sell over 10 million copies worldwide. Just incredible.
$159 in HMV. What are Dymocks playing at!? Ripping us all off, that’s what.
$159 at 7-11 on Elgin Street, plus you get hello kitty badges when you purchase over twenty bucks.
Sweet deal!
