Yes correct, here is the explanation:
At the time we started selling uniGUI we started a promotion with a product named uniGUI Plus. This product was the predecessor for uniGUI Complete.
uniGUI Plus had a price tag of 500 USD, while uniGUI Complete is 890 USD.
We continued this promotion for uniGUI Plus renewals later on. So those who started with uniGUI Plus promotional price and later switched to uniGUI Complete were still able to use the promotional renewal price (350 USD) which was lower compared to our renewal list price (550 USD).
Recently, I decided that it is time to switch all promotional licenses to standard license, because at some point we had to do this!
Now, all licenses are the same. Renewal prices are the same.
It was also difficult for us to maintain this double pricing policy.
I know that many of you purchased uniGUI when it was still beta. I'm thankful and I tried to continue the promotional price for a long time since 2014 when we started selling licenses. It is almost 5 years since then. I know, without your support there would be no uniGUI!
