Going through @High Endeavours comments on another thread, I see that he is the second person to have mentioned the Día supermarket in Puente de Domingo Flórez. I have been unable to find it, and it seems like it would be helpful to orient people walking through that town. But by doing some "google walking", I think I may have the answer. Is it possible that what is a Claudio supermarket in this picture from Google is actually the new Día? I think this is the most likely answer, since the Claudio supermarket pictured looks like it's empty and closed, and the picture was taken in 2012.
