Walmart offers the Patton Electric Utility Milkhouse Heater for $10.88. Choose in-store pickup to dodge the $5.99 shipping fee. That's $2 under our mention from last April, $6 off, and the best price we could find. It features front guards, thermostat, and a top handle.
The planet will thank you, your local (overwhelmed) landfill will thank you. Even your budget will thank you.
