As one of its daily deals, A4C offers the refurbished SanDisk 8GB Cruzer Glide USB Flash Drive, model no. SDCZ60-008G, for $19.99. This $20 mail-in rebate cuts it to $0. With free shipping, that's $6 under last week's mention of a new unit and the lowest total price we could find for a new flash drive by $7. Deal ends today.

A 90-day A4C warranty applies.
