Some bloggers report the tiff matter-of-factly but others, like Fishful Thinking, are clear Walgreens partisans:

Express Scripts' actions are causing disruption with no significant benefit to patients or their health plan. Patients covered by an Express Scripts plan not only have to change their pharmacists, but many are having to drive farther to get prescriptions filled at pharmacies with less convenient hours. As a working mother with a young family hours of operation is a huge issue.

What a waste on Express Scripts' part as Walgreens offers more 24-hour and drive-thru pharmacies than any other pharmacy in the country!!

Whatever the social media sites might do to sway public opinion, they're not likely to bring the two sides together. Speaking at an investment conference on Monday, Express Scripts Chief Financial Officer Jeffrey Hall said his company is ready to move forward without Walgreens:

At Express Scripts, we believe that the cost of healthcare absolutely has to go down as we go forward. And unfortunately, Walgreens' position is that flat is good enough and we really couldn't disagree more, and our clients are absolutely aligned with us and also agree that the cost has to go down over time.

As a result, our clients have been extremely helpful in working with us and moving business away from the more expensive participant in this network. And at the end of last year, we said we were confident that 95% of our script volume was going to continue into 2012 without Walgreens. We're a week now into the year. Obviously, a week doesn't make a year, but certainly, the trends we're seeing in the first week validate that, that we indeed are seeing that the scripts move away and we are more confident now that 95% of the script volume will continue without Walgreens.
