any reliable sources where i can watch studio ghibli movies?

i was first introduced to studio in my 6th grade conversational japanese class. and in those three years i got to experience two different teachers since our first one left to pursue a better career for herself(Mrs. Suzuki wherever you are i thank you for opening my eyes to the beautiful movies they created). four i remember we watched in class with either of those teachers are howl’s moving castle, princess mononoke, kiki’s delivery service and ponyo. i really wanna rewatch those four and watch all their other works too, seeing as i was like 11 or 12 back then and i’m 19 now, so the nostalgia and sentiment are definitely there for me. anyway folks, please drop some sources for me down below if anyone can, i’d much appreciate it :))
