Kmart offers the Route 66 Women's Jeans in Skinny Starlight, Slim Dark Rinse, Slim Medium Wash, or Slim Light Wash for $7.99. Even better, Shop Your Way Rewards members earn around $10 in SYWR points. (Not a member? It's free to join.) Opt for in-store pickup to avoid the $3.99 shipping charge. Assuming you use the credit, that's a savings of $18 and essentially a $2 profit. They're available in sizes 24 to 36, although not in all size/style combinations. Note that stock may be limited.
Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
