Amazon offers Prime members the SanDisk Ultra 64GB UHS-I Class 10 microSDXC Memory Card, model no. SDSQUNC-064G-GN6MA, bundled with a $20 Shutterfly Credit for $17.99 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise shipping adds $8.11. A promo code for the Shutterfly credit will be emailed to you after purchase.) That's tied with our March mention of the card alone as the best price we've seen for a SanDisk 64GB microSDXC card. (It's a current price low by $4; meanwhile, Adorama charges the same price for the card alone.) It features read speeds of up to 80MB/s.
