Walmart offers the Mainstays 2-in-1 Portable Heater Fan in Black for $19.99. Opt for in-store pickup to dodge the $5.99 shipping fee. That's $6 under our mention from a month ago and the lowest price we've seen. (It's the best deal now by $13.) It features 900- and 1,500-watt heat settings, two fan settings, and a recessed carrying handle.
