Walmart offers the Centon 32GB DataStick Pro USB 2.0 Flash Drive in Gray, model no. DSP32GB001, for $14.98 ($.47/GB). Opt for Site-to-Store pickup to avoid the $4.97 shipping charge. Outside of the deal below, that's the lowest total price we could find by $5, but we saw it in June for $5 less. It features an aluminum housing, plug cover, and connector for lanyards or keychains.

A close price: Amazon offers it for $14.98 with free shipping for Prime users.
