BuyDig offers the Samsung 16GB Pro UHS-I Class 10 microSDHC Card 2-Pack, model no. MB-MG16DA/AM, for $24.99 with free shipping. That's $13 per card and the lowest total price we could find for this quantity by $11. (For further comparison, we saw a single card with adapter for $15 last month.) Each card comes with a full-size SD card adapter and features up to 90MB/s read and up to 50MB/s write speeds.
