Well yeah. You can't redeem the T-Shirt outside of US and Canada, and TGI Friday's Gift Card won't do you a hell of a lot of good in countries that don't have TGI Friday's chains( link ). Also Netflix doesn't seem to be every country ( link ), so yeah. Clearly. Also I'm not sure which countries, but I've talked to several people like in India or South Africa, who tell me that Amazon is too expensive to ship where they live. So while you might be able to get your Amazon cards sent to your email, it might not do you a whole lot of good.
So yeah, with the maps an' all does that answer your question well enough?
