[DS] Your Nintendo DS Library

I've only got 4 DS games so far - that said, aside from the Metroid Hunters Demo, which I won't be colour-marking here for obvious reasons of irrelevancy.

Super Mario 64 DS
A very good rendition of such a classic, proposed in a fashionable change that makes good profit of the occasion. I particularly liked the alternative mini-games. While some of them were filler revisions of an identic formula, others really stood up for amusement factor and originality.

Yoshi Touch 'N' Go
The minimalistic essence of the new DS philosophy, or should I say, approach to gaming. In my view, this game represents a beautiful starting boost, an entertaining example of how touchscreen-based games should be developed.
The simplest idea, yet the most fun. And this game is endlessly fun to me.

Mario Kart DS
Need I to say anything about this jewel? It's the pioneer game of the Nintendo WiFi Technology and its tortuous tracks and improved mechanics make it a perennial blast to wage through. Fantastic.

Electroplankton
An unusual experiment, so much queer as effective in its intentions. Not even a game, as anyone would concur that this is more of a source of musical inspiration and, more generically, a way to soothe yourself in a very curious way of gameplaying. Geniality at its best.

And that's it. On a related note, I plan on buying many more titles in the days/months to come - but I'd like some help on the matter.
Could you, for instance, kind of direct me to some good e-site?

I'm looking for an online store that:
- has a proper selection of U.S. and Japanese Nintendo DS games
- reasonably-priced worldwide shipping through Airmail
- allows to mark packages on the famous GIFT/SAMPLE tags.

No clue so far, but thanks in advance for any help...
