Kmart offers the Route 66 Women's Midi Dress in Black or Skydiver for $7.99. Choose in-store pickup to avoid the $5.75 shipping charge. That's tied with our mention from two weeks ago, $12 off, and the lowest price we could find. It's available in sizes XS to XL, although not in all size/color combinations.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase.
