Looking for “Passageway” Doorknobs

Does anyone know of a local source for these?

In my quest at numerous ferreterías, Soriana, and Sam’s Club I have found deadbolts locks, bathroom locking doorknobs, and privacy lock doorknobs. I have been unable to find “passageway” doorknobs. These are simple twist doorknobs that don’t have a locking mechanism.

I have asked other residents who have confirmed that they are challenged in finding them.

I guess I could go online, but I’m hoping to buy locally.

As an aside, when I tried at Ferretería del Mar and at Sotelo, they each said that they didn’t sell any door hardware that was stainless steel. (My house is near the beach.). They each referred me to a new store that is just to the left of the Migración office.

I went there and I was able to get a deadbolt and a bathroom doorknob, but sadly no passageway doorknobs.
