Walmart offers the Secret Treasures Women's Satin Chemise and Robe Set in Black Soot, Lavender Sky, or Black Soot Animal for $10. Opt for in-store pickup to dodge to the $5.97 shipping charge. That's $8 off list and tied with our mention from ten days ago as the lowest price we could find. It's available in sizes L and XL, although not in all size color combinations.
