Is it a sale or is it like the new price forever? I read that they're giving rebates for the people who bought it for $50, which seemed fishy to me. Maybe they just needed some quick cash to carry them to where they could offer the app for such a cheap price. Like free credit.
It’s the new price forever. I think they just wanted to be the ones to see if a premium pricing scheme could work on the App Store, that didn’t go so well, and so they decided to go for a mass volume scheme.
