I'm paying the fee, too. Their website and phone app (especially the bar code scanner) make it super-easy to track everything, so I feel that it's worth every penny for the convenience. I'm doing the online-only program. I'm a very private person in real life, so the thought of going to meetings is terrifying! Plus, by paying a fee, I'm more likely to stick to the program, if that makes sense.
It's been so easy so far that I'm wondering what took me so long to sign up.
