Amazon offers the Eton The American Red Cross All-Hazard Radio / Portable Charger for $39.99 with free shipping. That's the lowest price we could find by $10. (For further comparison, we saw it bundled with two Blackout Buddies for $55 in October.) It's powered by a solar panel, hand-crank, or its built-in 2,600mAh rechargeable battery and provides weather alerts, music, and power for portable devices.

Update: The price has dropped to $37.18.
