Katy says: We maracuchas have our own little brands that we like to buy and promote. All else things equal, a true zuliano will always choose the local brand over the national one.
For example, for many years in Maracaibo a "newspaper" was called a "Panorama" because of the now-infamous chavista daily that, at least in our city, outsold all national papers combined; Banco de Maracaibo was the top bank in the city far and away, a title now claimed by BOD; Regional Beer and Cerveza Zulia outsold Polar; and so on...
It turns out that we also have our own supermarket chains in Maracaibo. Two of the most popular ones are Víveres de Candido and EnnE - yes, you've never heard of them, but any maracucho/a has, and they're pretty big.
Today I got a picture my sister took two days ago. Turns out the EnnE closest to her house was selling milk! Shows you what you have to go through to get milk in Venezuela, if you're lucky...
