Walmart has the 20" Lasko Weather-Resistant Motor 3-Speeds Box Fan for $19.87. The deal includes free shipping if you are a Walmart+ member or if your order totals $35 or more. This price is a strong deal for a weather-resistant, three-speed box fan, which typically retails for higher prices. The lower price point makes it a practical purchase, especially given the weather-resistant features. Since Walmart+ offers free delivery, this adds convenience, though minimum order requirement exists for non-member shipping. Overall, the deal provides a solid savings on this fan, especially for those who qualify for free shipping.
