Kobo only sells their products in USA at independent book stores. That's a joke and failed strategy because last one I know maybe still selling them is Politics and Prose in Washington D.C. .

You can buy them from Kobo web site or from Canadian stores. if you don't like what you bought send it back. Shipping charges you might loose is less than driving to Washington D.C.
