B&H Photo-Video offers this Kingston 16GB Class 4 microSDHC Secure-Digital High Capacity Card, model no. SDC4/16GB, for $9.95 with free shipping ($0.62/GB). (Buy.com charges pennies more.) That's the lowest total price we could find by $2. (We saw it for a buck less in March; however, that deal required a mail-in rebate.) It includes a full-size SD card adapter. Deal ends May 31.
