Nooooooooooooooo... I bought the Intellij IDEA 12 upgrade 3 days ago... I paid 111€ (including VAT) instead of 27€... I now it's irrational, but I'm sad.
I paid 111€ to upgrade (94€ + 19% french VAT). If I were to upgrade now, it would cost 27€ (23€ + 19% french VAT).
I wonder if I should just cancel the upgrade and buy a new license. According to the terms and conditions on the Digital River website, I have a legal "cooling off period" of two weeks.
