I just got an auto-renewal for ZAES for $59.95. I have no proble paying for renewals, but I can buy it new for $49.95 (yes, I know, it's the 'special' price, but they always have a 'special' price).
So, logic says to cancel the renewal and buy the new copy. Jeez, a lot of trouble for everyone.
I think the renewal cost should be less than the price of a new purchase, say $39.95 or less.
