Newegg offers the SanDisk 64GB Ultra UHS-I Class 10 microSDXC Memory Card with Adapter, model no. SDSDQUA-064G-A46A, for $29.99 with free shipping. That's $18 below our mention of a similar SanDisk model and adapter from last summer and the lowest total price we've seen for this memory card. (It's a current low by $5.) It's UHS-I enabled and comes with a full-size SD card adapter.
