I haven't done this either.
As others have said, I would be mad at myself for spending money on something I'm not using (gym membership, anyone?).
I have bought a few classes on Craftsy - and have watched them several times - but I have my own little quirks about what I'm interested in, and lately, nothing on Craftsy has been appealing. But my focus may change 6 months from now, and I may buy 2 or 3 classes back to back.
But $120 worth? Nah, I'm averaging maybe one class per year right now.
And with spring and summer around the corner, that means vegetable gardening will take a lot of my time soon.
