BuyDig offers the Samsung 32GB Class 10 microSDHC Secure Digital High-Capacity Card, model no. MB-MPBGCA/AM, with an SD Adapter for $19.95 with free shipping. That's the lowest total price we could find by $8. (For further comparison, we saw the card without the adapter for the same price via in-store pickup in January.) It features read speeds of up to 45MB/s and write speeds of up to 13MB/s.
