My partner works in the pharmacy industry and told me some interesting news about MedAdvisor that was reported in the AJP.
In their half year presentation it was announced that they would start charging for transactions for vaccinations and ProjectStop.
While pharmacies will have an option on how they manage vaccinations, ProjectStop is a mandated government initiative in a majority of states to prevent pseudo shoppers and was incorporated into MedAdvisor when they acquired GuildLink then rolled into the PlusOne platform.

If MedAdvisor start charging pharmacies per transaction in which they have no choice, they can likely expect some disgruntled customers and for me is a bit of an ethical grey zone.
Pharmacies may then also either stop using the program in the states where they don't need to, reducing the positive impacts it has had, or just stop selling pseudoephedrine-based products.

But also an example of pricing power in play.
