Samsung Pro Micro SD 64GB (USD $29.99 + $12.26 Shipping - Roughly AUD $56 if paying by PayPal @B&H Photo)
This is the model: MB-MG64EA/AM (which is U3 model).
Shipping is bit steep, but overall, cheapest i have seen for U3 model for far. Hope they send me the correct model.
Think B&H has dropped the price on this recently, and the rise of Aussie dollar has made this purchase viable.
can get the same card from Amazon for $47.20AUD delivered.
