As one of its Black Friday ad deals, Best Buy offers the SanDisk 128GB Ultra Plus Class 10 microSDXC Memory Card for $19.99 with free shipping. That's $10 under our mention from a year ago and the lowest price we've seen. (It's also the best deal now by $15.) It includes an SDHC/SDXC adapter and features read speeds of up to 80MB/s. (It also includes a free Shutterfly Book or $25 gift voucher.)

We recently named Best Buy one of the best stores for Black Friday deals this year. You can read our full Best Buy Black Friday guide here.
