But that's not all. If you are planning to buy more than one of a particular model, you get volume discounts. Click on the blue "Buy more" at the aforelinked Adorama pages to see a tiny pop-up with the volume discount details. For example, if you buy two of the aforementioned 16GB Extreme SDHC Class 10, you pay $25 per card instead of $26.50. If you buy three or more, the per unit price is $24.70.
