Sears offers the Joe Boxer Men's Plush Bathrobe in Plaid (pictured), Black or Grey Stripe for $14.95. Coupon code "CLEAR30" drops it to $10.49. Opt for in-store pickup to dodge the $5.75 shipping fee. That's $5 under yesterday's mention and the lowest price we've seen. (It's also a current low by $35.) One size fits most.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts. Plus, Shop Your Way Max members are eligible for free shipping.
Update: If you prefer, the Joe Boxer Men's Fleece Bathrobe is available in four colors at the same price via the above coupon.
