Shipping is free in the US but costs a ludicrous $60 to ship a couple of memory cards to Australia. I guess the only way this deal can work is if there is a cheap mail forwarding option for low weight items, or if you're in need of enough of these to make the shipping costs less of an impact.
Been looking around and one option is to use Reship.com - free account sign-up (saves $5 using code UNLOCKED) and then pay about $15 using USPS for shipping - posted as separate deal here : https://www.ozbargain.com.au/node/144374
