We have a few hundred DSTT flashcards for Nintendo DS and DS Lite available at http://www.modstuff.com.au. DSTT is pretty highly regarded in the modding community for its affordable price. Great if you only need a basic flashcard. I'm pretty sure we have the cheapest DSTT cards around in Australia. But shop around. I'm happy to price match :)
Here's what we have on special (after discount coupon):
DSTT Flashcard for DS & DS Lite - $20.25 http://www.modstuff.com.au/toptoy-dstt-for-ds-lite
DSTT + 2gb MicroSD card + reader - $27.56 http://www.modstuff.com.au/dstt-multimedia-card-2gb-microsd

USB MicroSD card Reader - $1.5 http://www.modstuff.com.au/microsd-card-reader.html
I've noticed Ozbargain is often critical of flashcard deal posted in the past. I'm sure a few of you might mention some HongKong Site such as dealextreme. Here are few reasons why you should buy Australian:
1. Much faster shipping and handling time. Most of the time, items are dispatched on the day we receive the payment. 99% of the orders can be delivered in less than a week. Melbourne delivery is overnight.
2. Local customer support.
3. Customer service in large online department stores are not trained to handle inquiries related to specific product. We specialise in flashcards and we know our products well.
4. Dealextreme is a great site (I get my Cree torches from them), but they have stopped selling flashcards since November 2009.
Meh, they're "wholesaled" at about 5 bucks.
