Orange Onions offers Two Eco-Friendly 12.5-oz. Ceramic Mugs with Silicone Lids for $9.99 plus $6.99 for shipping. Better yet, add two to your cart and apply coupon code "COFFEE" to cut the price for both to $14.99 with free shipping. That's $3.75 per mug, tied with last week's mention, and $17 below the lowest total price we could find for four similar 10-oz. cups. These eco-friendly cups feature silicone bands.
