REI ( www.rei.com )carries Luna Bars (among other yummy energy bar treats) and ships world wide as far as I can tell. I don't know if they have restrictions about shipping food items, but it might be worth a try. None of the energy bar/drink companies are in the list of brands that can only be shipped to the US and/or Canada so I suspect that you probably can get them.
the international shipping rates are fairly high so you'd have to order a lot to make it worth it - maybe you could get together a bunch of people who want to try them?
