Not true. As with anything, or any place, there will be dishonest people who prey on the innocent. But they are fewer and almost non existant in Medjugorje. The overwhelming majority of people in Medjugorje charge very little for what they do or for what they sell.
The people there live simply, and never take advantage of anyone. I have seen shop keepers running down the street after someone who paid too much. I have seen wallets returned to our pilgrims full of money by taxi drivers. I think the best way to sum it up is to say that it is the most honest place to visit that I have ever been. I have never been cheated, and actually quite the opposite. People are always giving you something extra, and with a smile. The local people there work to supply visiting pilgrims with what they want in the way of food, clothing, rosaries, statues, etc. They work to make their stay more comfortable. There is certainly nothing wrong with that.
