Purdue was doing it at one point. May want to reach out to them?

This can be a hard one to get traction on. In my case we had Amazon drivers and subcontractors dropping off packages in our mailroom that should have instead been delivered to offices around campus. I ended up searching for contracts Amazon had with other agencies in the state, found one for a neighboring elementary school district, and used the contact information found there to address our concerns.
It still took a bit of work, but if your state has a database of contracts that might be a way to go for an initial contact at least. The folks in our purchasing department helped me sniff out the one I used so your purchasing folks could be a resource on that front too.
