Kmart offers the Signature by Levi Strauss & Co. Men's Straight-Leg Jeans in Beige or Brown for $21.99. Plus, Shop Your Way Rewards members will earn around $20 in SYWR points. (Not a member? It's free to join.) With $5.75 for shipping, and assuming you'll use the credit, that's the lowest total price we could find by $13. (In-store pickup may also be available.) They're available in sizes 29 to 38 with 30 to 34 lengths, although not in all size/color combinations.
Note that the points expire after 14 days. Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
