Walmart offers the Secret Treasures Women's Sleep Shirt 2-Pack in several styles (Bardot Pink/BSL pictured) for $7. Opt for in-store pickup to cut the price to $6.50 and avoid the $5.99 shipping charge. That's $1 under last week's mention, $4 off, and the lowest price we've seen. They're available in select sizes from S/M to 2XL/3XL.
