Walmart offers the Proctor Silex 1.7-Liter Cordless Electric Kettle in Black for $11.90. Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest price we could find by $11. It features a lift-off base, boil-dry protection, 1,500-watt heating element, lighted on/off switch, and automatic shutoff.
