Hi Mandy.
I just signed up with LAWL at the end of October and agree that it can be expensive. Especially if you get sucked into buying their supplements and bars. Fortunately for me (haha) I have an as-yet-unidentified blood disorder. The existence of which prompted them to tell me that I was not allowed to use any of their bars or supplements.

Not that I would have opted for them anyway. I felt that they were nothing more than a way for them to up their profits.
So after a little over three weeks I've been about 95% on plan, no bars, etc. and I've lost almost 15 pounds. That tells me that I don't need any of the extra stuff they are selling. I just need a place were I can go to weigh in a few times a week for accountability. LAWL provides that. Yes, I pay them for the privilege but I'm OK with that as I am the one who is ultimately benefiting from it. I pay them but I don't have to overpay them.
I have friends in another city here who just refused to buy the Lites when they signed up. The person at the centre tried to insist but my friends were firm and that was that. I'm sure it varies between centres but you could always try another centre if the one local to you tries giving you the hard sell.
Now is a good time to join as they are offering the plan at 50% off. Here in Ontario at least.
Good luck with your decision!
