Question about the Online Store

Greetings.

I wanted to ask if there is any method through which I can request that the online store where in my local currency, and what steps should I or we (the clients of this country) follow to make such a request?

In case there isn’t some formal way to do it, I hope that this post can serve as a record (even if it comes to nothing) of interest in a store in Guarani, the local currency of Paraguay.

Thank you in advance for your time.
