Adorama offers the Samsung 64GB Ultra UHS-I Class 10 microSDXC Memory Card, model no. MB-MGCGBA/AM, for $29.95 with free shipping. That's $24 below last October's mention, $20 under the best price we could find today, and the least expensive Samsung 64GB microSDCX we've seen. (For further comparison, we saw two for $37 more in May.) Features include 70MB/s read speeds and 20MB/s write speeds.
