As one of its daily deals, Amazon offers Prime members the SanDisk Ultra 64GB UHS-I Class 10 microSDXC Memory Card (pictured), model no. SDSQUNC-064G-GN6MA, for $17.99 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise shipping adds $8.) That's $7 under our mention from last August and the lowest total price we could find now by $2 and the best price we've seen for a SanDisk 64GB microSDXC card. It features read speeds of up to 80MB/s.

Also available for Prime members is the SanDisk Ultra 32GB UHS-I Class 10 microSDXC Memory Card, model no. SDSQUNC-032G-GN6MA, for $9.99 with free shipping. (Non-member shipping is as above.) That's the lowest total price we could find by $3 and the best we've seen for a SanDisk 32GB microSDXC card. Both deals end today.
