Where can you watch all seasons of Adventure time?

I'm looking for a platform similar to Netflix where I can watch Adventure Time. Netflix unfortunately only has d4 seasons. I would like to buy the DVD with all seasons because it is very expensive. You would also have to buy the seasons with Amazon Prime.

Does anyone know a platform with a subscription option?
