There are a lot of queues, and the girls are not in a hurry. I asked for one ampoule each for a sample. I counted several pieces, I say, if necessary, we will buy them. With the words "everything is fine" and removed, I say "that you do not sell" only after they answered that they do not sell pieces. Very slow and not polite girls. In all pharmacies they sell by the piece, if they do not sell there, then you need to notify them in a prominent place
