VAT-IVA just went up! What about tour prices?

<p>
  VAT* IVA* was raised tonight at midnight, effectively 7.1% more. Though presented as a move from a previous 14% to the new 15% rate.<br />We knew this punch was coming by the newspapers, but the craziness is that this law was published at 5pm, meaning that you have as a business 7 hours to adapt.<br /> Now let's imagine the 10 million people that will see in just 7 hours prices going up and the invoicing software that will have to be update today, July 1st.<br />But worst, the huge amount of people that will still invoice with the wrong VAT rate.

I personally believe that this is the shortest

Now what about Wind Birds tours?
We will take this punch in the stomach and??no prices will be raised.
