Try Costco pharmacy to see if they charge less than regular drugstores. I found Florastor there, same number of capsules, same name, but $25 less than my regular drugstore. They also carry brand name drugs under their own Costco branding. I found my allergy medicine, Claritin and Reactine, but under a completely different name, same ingredients. The pharmacist at the counter confirmed this. It was almost $20 less for the box!
