This is madness. XD Less than a month ago I sent a local pharmacist into a panic fit asking her about cups, and now here they are!
So, here's some other info (remind that everything will be in Italian here):
The store: NaturaSì, il Supermercato della natura
The Italian distributor for the Mooncup: La Bottega della Luna
I hope this helps, I know one of the major issues here is to actually find the cups, not everybody likes buying on-line. And of course let me know if this is inappropriate and I'll remove the post!
