About a week after I finally persuaded myself to get Fantastical 2 for the Mac, it dropped in price. For most software I wouldn’t care, but when it’s $50 to start with, that $10 price drop is significant.
Now technically Apple doesn’t have any price guarantees.
Prices for products offered via the Services may change at any time, and the Services do not provide price protection or refunds in the event of a price reduction or promotional offering. via Apple
However, I wrote them and asked if there was anything they could do. They decided to refunded me the original price so I could re-purchase it at the lower price.
I don’t recommend doing this often, but if you do buy some software from the Mac App Store, then it drops in price, the option is out there.
Can’t hurt to ask right?
