I bought one at a local store, and went on Amazon to check the prices.
Well, Amazon's selling the SDHC memory cards way cheaper than stores in Singapore, even after you factor in shipping charges. Buy more that US$125 and shipping is free to Singapore.
Transcend, Sandisk, Sony, UHS-1, Class 10, whatever. If not for the GST, camera lens are cheaper too.
I'll just buy a few backups to put in my wallet. They work well as storage devices for files.
