Walmart offers the Secret Treasures Women's Sleep Shirt in several colors (Black Soot Up Owl Night pictured) for $4. Opt for in-store pickup to dodge the $5.99 shipping fee. That's slightly under our mention from two days ago, $1 off, and the lowest price we could find. It's available in select sizes from S to 3XL.
These freebies are available to anyone with an internet connection, including both Amazon Prime members and nonmembers.
