I got a $10 gift code by email after my KT purchase in Canada.
I used it to buy "A History of the World in 100 Objects" (Canadian version:
http://www.kobobooks.com/ebook/A-His...Apw/page1.html), for just over $10 (with a promo code).
Fascinating book, but it seems to be listed as "Not available in your country" if I use the U.S. link:
http://www.kobobooks.com/ebook/A-His...67w/page1.html. Odd, Amazon.com has it in Kindle format, although it's $20 ...
Ironically I found the large color illustrations made this ebook fairly unreadable with the KT, so I ended up reading it on my larger color tablet instead.
