Purchasing Twitterrific from the Mac App Store (Mac)
Can I purchase Twitterrific from the Mac App Store?
Yes, Twitterrific is available from Apple's Mac App Store here. Keep in mind that if you purchased Twitterrific from the Iconfactory website, there's no way to convert or upgrade to a Mac App Store purchase. You will get auto-updates after you purchase from the Mac App Store. To re-enable the “Purchase” button in the Mac App Store, just drag the app to the trash and empty your trash.
