It's fine to suggest sites. I personally ordered my DSTwo from www.kickgaming.com . They're based in Toronto,Canada, although they ship to the USA. It took about 3 days for my card to come with the basic shipping, and I've ordered from them in the past with similar shipping times. Mind you, I live a bit to the south in the USA, so you shouldn't have to wait too long to receive your card from them.

 

You should keep your order, as ShopTemp said they'll ship it if you were able to buy it.

I recommend nds card sale (put them together) dot com. Cheapest, but you'll need to wait a month for your stuff to arrive.

Also they will inundate you with newsletters and crap, but you can opt out once they send you the first email.

Oh on further look it seems they aren't the rock bottom price for the DSTwo. $35

I do recommend that $2.99 R4 though. Been using that exact same one for a year now with Wood and it works great no complaints.
