Walmart shoppers score huge discounts on popular items at checkout.

Walmart is selling a highly-rated Anker Eufy robot vacuum cleaner for just $96, which is more than 60% off its original price. The vacuum is Wi-Fi-connected and has three brushes for different floor textures, allowing it to memorize a space for maximum cleaning capacity. The lithium-ion batteries inside the robot allow it to clean floors for up to 100 minutes. Walmart has also marked down other essential appliances, including a portable air conditioner and a baby swing, both available online and in select stores. Customers can take advantage of Walmart's online price-match policy to get the same discounts in-store.
