Walmart offers the Mainstays 2-in-1 Portable Heater Fan in Black for $14.97. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with our mention from two weeks ago as the lowest price we've seen. (It's the best deal now by $12.) It features 900- and 1,500-watt heat settings, two fan settings, and a recessed carrying handle.
