Hi, Robert. I can’t vouch for all stores in Mexico. I think a lot has to do with where you’re located. I happened to be near a tourist area that caters heavily towards the cultures and foods of the tourists. For me, it’s fairly easy to find anything I could want. However, if I were in a small town in rural Mexico, I think I’d really have a challenge. My suspicion is, a fancy store in any medium to large Mexican city will likely have what you need, but it may take some sleuthing …
