Elektra supermarket in Mexico recently started accepting Bitcoin payments and is encouraging their clients to do so, as they offer a 20% discount when paying with it (until end of the year).
Here's the promo banner (in Spanish):

Now people in Mexico are able to buy groceries, and retail in general using Bitcoin directly.
An interesting thing to consider is that the parent company, Grupo Elektra, has operations in these countries: Mexico, US, Guatemala, Honduras, Peru, Panama, and El Salvador.
