As one of its daily deals, Amazon cuts up to 72% off select SanDisk memory cards and USB flash drives, with prices starting at $16.99. Plus, Amazon Prime members qualify for free shipping on all items. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping starts at $8.02.) That's among the best sales we've seen on these items from Amazon in recent months, although we saw up to 75% off a similar selection in October. Sales tax is added where applicable. Deal ends today.

A best bet is the SanDisk 64GB Ultra UHS-I Class 10 SDXC Secure Digital Extended Capacity Card (pictured), model no. SDSDU-064G-AFFP, for $41.99 with free shipping ($0.66/GB). That's the lowest total price we could find by $9. (We saw for $9 less on Cyber Monday, but it quickly sold out of stock.) It features transfer speeds up to 30MB/s.
