B&H Photo Video offers the Lexar 64GB Class 10 UHS-1 633x High Performance microSDXC Memory Card and USB 3.0 Reader for $43.95 with free shipping. (Amazon offers the UHS-3 version, which features identical performance, for the same price.) That's tied with last month's mention and the lowest total price we could find by $25, outside the price below. It features a maximum read speed of 95Mb/s and a minimum transfer rate of 10Mb/s

A close price: Adorama has it for $44.95 with free shipping.
