Amazon just dropped the prices on their most popular Transcend SD memory cards which are prime / FSSS eligible:
32gb Transcend for $16.99 Class 10 SDHC Flash Memory Card.
16gb Transcend for $8.99 Class 10 SDHC Flash Memory Card.
This is the lowest price ever as far as camelcamelcamel is concerned. It's an excellent deal for those who just bought the Olympus XZ-1 camera which is on Amazon for a steep discount at the moment (see the Olympus XZ1 for $199.99 from Amazon thread here)
