Here everyone, the mystery of the expat Medicus plan is solved: http://www.expat-connection.com/localins
There would be no significant savings for me unless they've magically frozen the prices to be inflation-proof. Whether you have to go to Expat Connection events or pay a membership fee with them remains a mystery. The event calendar has been empty since April 2012 and it looks like the rest of the site hasn't been updated since 2009. No surprise there. But if I weren't planning to be out of here by the end of the year at the latest, I'd definitely write to them and get more details.
