Radio Shack offers the SanDisk 64GB Ultra UHS-I Class 10 SDXC Secure Digital Extended Capacity Card, model no. SDSDU-064G-A11, for $39.99 ($0.62/GB). Opt for in-store pickup to avoid the $6.99 shipping fee. That's the lowest price we could find by $10, although we saw it for a buck less shipped in August. Sales tax is added where applicable. It features read speeds of up to 30MB/sec. Deal ends November 24.
