By the way, this not only applies to Dollars, but also to other currencies like Euros (Although we barely buy those, since we don't need them).
We also have problems buying online, for example, if I buy something on Steam, since the money is going outside of the country, I have to pay 20% more in taxes (I think that's the correct number) although we get the official dollar price.
The official number is definitely way cheaper than it should be. If it werent, the government would not need to prohibit currency exchanges because the income/outcome of dollars would be balanced.
Credit card dollars are a huge opportunity, thats why its becoming the N1 concern for the government.
