Title pretty much states it. 3 x 2gb Integral MicroSD cards for 8GBP (12AUD)
Postage is £1.95 - Registered £8.95
I'd recommend using registered and buy some other stuff at the same time - you'll save money (post is flat rate, not calculated by weight or anything)
Your wording is somewhat confusing (edit: removed as you've updated).
Regardless I fail to see the need for 3 cards and it isn't really cheap either. You can get an 8GB MicroSD from MSY for $15 or 2GB at $6…
