Try not to go SLS unless you're very sure of what you're doing,
and you know how to bargain and know how to relate to them
well.
They will try their best to cut your purse, but if you're good
enough in your speech, you can grab quite a few good bargains. For
the SD card, there is a IT show going on now, maybe you can gather
up a friend living near there to buy one for you? I don't know if
they are selling NDS : L at the show, I doubt so though.
Have fun with the NDS : L, I love mine
