Amazon offers its Prime members the Samsung EVO 64GB microSDXC Flash Card, model no. MB-MP64DA/AM, for $24.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $8. Adorama and TigerDirect charge the same.) That's tied with our expired mention from four days ago and the lowest total price we could find by $4. It includes an adapter.
