Hmm... The SanDisk site says "The SanDisk Eye-Fi Wireless Memory Card is available in select countries within Europe, the Middle East, and Africa only.", so I don't think it'll be easy to find locally. Looks like it is available in 8Gb and 4Gb only. I might be mistaken, but the SanDisk Eye-Fi cards are rebranded under licence.
If you don't mind the price, you should get the Eye-Fi 16b Pro X2 card which is like saberlancer pointed out, is a much faster card. Or Transcend, which has a 32Gb Wifi SD card. Personally I'm using the Eye-Fi 16Gb Pro X2 in my Pentax WG3 GPS and it works like a charm.
