As one of its daily deals, A4C offers the refurbished SanDisk 4GB Cruzer Blade USB 2.0 Flash Drive, model no. SDCZ50-004G-A46, for $2.49 with free shipping. That's a buck under our December mention and tied as the best price we've seen for any 4GB USB drive. (It's also $9 below the best price we could find for a new one.) It comes with SanDisk SecureAccess software for 128-bit AES encryption. Deal ends today.

Note: A 90-day A4C warranty applies.
