We had steady growth of IDNs before we reduced prices and we have it now... So the general trend is not correlated with price.
Price matters, but if we talk about aftermarket sales of the names for a
few hundred euro, it doesn't matter if renew price of the domain name is 2-3 or 9-10 euro.
But of course I'm glad that
NASK reduced prices for IDNs in Poland, because we did everything we could to support it. Another story is if it was successful or not...
I hope other TLDs will learn from .PL how to deal with IDNs
