Walmart offers the Lasko 16" Oscillating Floor Fan White for $19.99. Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest price we could find by $6, although it was a buck less in September. It features a 32" to 47" adjustable height, three speeds, and tilt-back head.
With these companies, it might be easier than you think to negotiate your monthly bill down.
