LauKingdom via Amazon offers Prime members the LauKingdom 8x7.9" Cast Iron Cleaner for $15.99. Coupon code "94SIKF62" drops it to $9.99. Plus, Prime members bag free shipping. (Non-members can spend $35 to bag free shipping; otherwise, it adds $6.63.) That's tied with our December mention and the lowest total price we could find by $16.
