My niece (not actually much younger than me) has moved to Canada with her two children. Rather than waste money packaging and sending presents they don't want and can't return, does anyone know where I can buy a sort of international gift voucher? Does such a thing exist?
don't get iTunes cards online, unless you have an account with Canadian iTunes, or unless you buy physical iTunes cards from ebay or somewhere else and have them posted. Normal UK itunes cards/gift certificates (even online) won't work in the itunes store of another country.
Amazon also has to be country specific to be useful - you can use UK ones from Canada but have to pay all the extra postage. I don't find amazon.ca has as much as the uk site, but still has a lot.
chapters/indigo is good for books etc.
Lots of shopping malls do gift certificates that can be used anywhere in the mall, so if you can buy those online, that would be a good bet.
