Renita from what I understand you can join Jenny for 399.00 and that is either a year or lifetime, I am not quite clear on that. But you can also wait and join with one of those specials they run like the 20 pounds for 20 dollars deals. Either way you still have to pay to join and then pay for the food.
All the foods I have found are normal grocery store foods and include everything from lean cuisines, regular cookies, healthy choice soups, and even just a plain old piece of grilled chicken breast on a 100 calorie Wonder Bun. Some of the nutrition info on the foods does not match exactly but I tried to find the closest thing I could that was available in a mainstream store and you did not have to go to a special health food store or anything.
If you want more information send me a pm with your email and I will send you a link to the info
