Amazon offers its Prime members the SanDisk 32GB Ultra UHS-I Class 10 microSDHC Memory Card with Adapter, model no. SDSDQU-032G-AFFP-A, for $19.99 with free shipping. (Non-members can spend $25 or more to get free shipping; otherwise it adds $8.) That's $0.63/GB and the lowest total price we've seen for a card of this class since May, when we saw one for $5 less. It's UHS-I enabled and comes with a full-size SD card adapter.
