I am not sure what you are referring to - there was no recent price increase: Acrobat Pro has been $449 for a while. Is it possible you were trying to lookup Acrobat Standard? That is still sold for $299.
I sure missed the price increase, when ever it was. The last time I looked (quite a while back) it was $299 and the upgrade was $199. At $449, it becomes a real question of who would be purchasing it. That is really out of the ball park for many personal users. If I was looking at it the prices to purchase, I would very quickly be looking for an alternative since I do not need most of the things that Acrobat offers, though I use many of those since I do have the product. I am really wondering what customer base they are trying to market to. Even for small businesses, $299 was a big expense.
So I guess I am expressing a concern. It is no wonder that so many folks try to use their old version on new machines, even if not optimal.
Subscriptions remove a LOT of this concern for the average user.
For the Enterprise, they are buying “in bulk” and the price comes down…
