Both Udemy and GameDev.tv have very good tutorials and you can get them on sale for about $10 or so every now and then, especially in Humble Bundles. I've been taking several of their blender courses and it depends on what specifically you want to learn. An excellent overall Blender course is The Blender 2.8 Encyclopedia. It covers many subjects, as the name implies. It is constantly updated whenever Blender comes out with new stuff. Their Unity 3d course is the best. I took it for over a year because there were so many lessons and I learned a great deal.
