Walmart discounts a selection of toddlers' and kids' slippers, with prices starting at $2.88. Opt for in-store pickup to avoid the $5.99 shipping fee. Note that prices vary by size for many styles. A couple of best bets, both available via pickup:
Lands' End offers its Lands' End Men's Fleece Clog Slippers in Black or Classic Navy for $11.99. Apply coupon code "FAMILY" and "5000" to drop it to $8.39. With $8 for shipping, that's $13 off list and the lowest total price we could find. It's available in sizes 8 to 13.
Tanga offers the James Fiallo Men's Indoor/Outdoor Quilted Suede Loafer Slippers in Black, Tan or, Brown for $9.99 with free shipping. That's $30 off list and tied with our mention from three weeks ago as the lowest total price we could find. They're available in sizes XL and XXL only, and not in all size/color combinations.
