I was a bit confused on this as well. From the recommendations section, here's what I'm ordering:

Nature's Way Primadophilus Reuteri Pearls, 60 Count

Culturelle Daily Probiotic Formula, Digestive Health Capsules,30 count

Align Daily Probiotic Supplement, Probiotics Supplement, 42 Capsules

Bi2Muno Prebiotic Food Supplement 30 Sachets

The total order comes to about $75.
