The Wonder-Bag at Amazon

Instapundit recently noted that Amazon is selling the Wonder-Bag--an insulated bag that uses retained heat to complete the cooking process (and saving your cooking fuel)--aka, insulated cooking. Back in December 2011, I posted about the Wonder-Bag when it was first marketed in South Africa, as well as DIY resources for insulated cooking, including making a "hay box," or using a Thermos or vacuum flask systems.
