@lindac61 I also take Florastor or another brand of S. Boulardii every single day. I googled the Dificid coupon but the site that I went to where it said it would be $50 also said that those on Medicare were NOT included in the offer. Not sure why because even with our Medicare and Humana RX plan, my deductible was still almost $1,000. My GI prescribed it through a cancer center pharmacy and they found a place that helps with high RX's so I only had to pay $78. When it was through Walmart, it would have been a little over $1,000 copay.
