I will say it briefly and clearly.
Minuses :
1. It's expensive
2. Most people are not literate about their work.
3. You come up and ask trimol (if they don't have it), they offer a substitute type of cupen, although at first they won't say we don't have one, because our main thing is the economy. I gave you an example about painkillers.
Those who know what's what, they don't take it, and the rest who don't know about the medicine are fine and we have such a lot of noodles for them and they don't knowingly buy.
This is my personal opinion.
