Walmart offers the Essentials by Isotoner Men's Microterry Slip-On Slippers in Brown (pictured), for $4. Opt for in-store pickup to avoid the $4.97 shipping fee. That's $3 under last month's mention and the lowest price we've seen. (It's also the best we could find for any such slippers by $14.) These machine-washable slippers are available in sizes S to XL.

Of note, Walmart also offers them in a slightly different style in Black or Charcoal for the same price.
