Amazon offers Prime members the Mastrad Silicone Oven Mitt with Cotton Lining in Green for $10.98 with free shipping. (It's a buck more in Blue; non-members can spend $35 or more to qualify for free shipping.) That's the lowest total price we could find by $5. They're heat-resistant to 480° F and feature a removable cotton lining.
"These are the old Orka oven mitts. Love 'em, use them at home." -- Dan de Grandpre, CEO
