CreativeLive is a great, though pricey, online education platform. Videos and trainers are top notch, and they have about 5-6 courses a day streaming live for free, while you can buy any to keep. The iOS app also lets you preview the first 30 secs of any class segment, or you can watch one whole class segment for free a day.
Areas include:
Photo & Video
Art & Design
Music & Audio
Craft & Maker
Money & Life
The site has further sales 5am-5pm though probably not as good as 50% off. This is a price only once or twice a year.
Prices in US dollars
Probably not many fans here, but I can tell seen some of their photographic courses and can only recommend them. While I think one course was lets say below the average, the others I had were really good. Mind you they are in a form of a day course filmed on a video.
Incomparable to the free Udemy courses.
