Panera Bread is doing its part to increase breast cancer awareness in October by offering customers a great perk. To help the cause, purchase a 2015 Pink Ribbon tumbler for just $10 at the popular bakery shop, while supplies last. Then, bring the tumbler into any Panera Bread in Colorado and receive FREE unlimited brewed coffee refills through October 31. It’s even more of perk because the net proceeds benefit Rocky Mountain Cancer Assistance. Of course, the sooner you buy a tumbler, the more refills you can get.
