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.

https://en.wikipedia.org/wiki/Grupo_ElektraThat means that they already accept Bitcoin directly from at least 2 countries: Mexico, and El Salvador. Some of the other countries in that list could potentially be the next one.
since they are accepting also In El Salvador meaning this business originated in El Salvador and not in mexico?
also if this is a physical store then Yes this is a great achievements for cryptocurrency having 2 countries accepting Bitcoin directly from their wallets.
but Congratulations to the people who will use this offer as 20% off also is indeed to be taken .
