It's certainly more cost effective than buying the CS6 version. We can get discounted options for a monthly commitment of one year, or if we prepay for the whole year. If we want to use Photoshop for a single month, it will cost us $29.99. The latest Creative Cloud (CC) versions are only available as Adobe subscriptions. Since 2013, Adobe changed its pricing model, turning Photoshop into a pay-as-you-go service.
The extended CS6 edition could go all the way up to $2,599. The last standalone version, CS6, started at $699.
