I signed up for my free kit! Thanks for the link.
Quest also has an offer for 2 free bars. Look at how natural the ingredient list is. The words are pronounceable, actually contain everyday foods instead of chemical-sounding stuff, plus they're Splenda sweetened:
Protein Blend (Whey Protein Isolate, Milk Protein Isolate), Chicory Root Fiber, Peanut Butter, Dry Roasted Almonds, Water, Raw Almonds, Peanuts, Natural Flavors, Sea Salt, Lo Han Guo, Sucralose.
