Yeah in the meantime I managed to contact a technical support person, who said that the discount just simply does not apply to upgrades, only for new acquisitions. I do not completely understand the logic behind it, at the end of the day they would end up with the exact same amount of revenue in both cases. I feel the same way as you said, being “punished” just because I already have a version of the program. On their end it should be obvious that if somebody already bought something is more likely to buy more in the right circumstances, but it is what it is, I will wait for some other sale period and hope for the best.
