With Jenny I buy the snacks, dinners, dressings and my cost avg. $140/wk. I could go cheaper and cut out some things. But that works for me. In addition, I have to purchase my fruits and vegetables in addition to milk. I think Jenny may be a little more expensive, but I like the food better and you also get the one on one meeting once per week. As far as incentives from each program, I think Jenny offers more. I go to a local center, which the mail order I couldn't tell you how good that is. If there wasn't a local center I don't think I would do Jenny. I like the face to face contact. I lost 14lbs in 5 wks. Things are going good so far.
