I love the craftsy classes! I am a single mom wiht not a lot of extra time. Most of the classes at the LQS are during my work hours. I can watch Craftsy at home on my iPad (and my kids like to watch along). It's most convenient to me. I suggest trying a free class and seeing if you like it before purchasing a big class. I bet you'll be hooked like the rest of us!!
I *always* buy the classes on sale and many of the instructors have dicount links on their blogs. I have never paid ful price for classes. I've even gotten a refund for a class or two and it was SO easy. No questions asked, though I did provide my reasoning.
Good luck and happy quilting!
