I ordered some clomid and nolv from an online Mexican pharmacy (medsmex.com), and I just got a "missed delivery" notice in my mail from the post office. It says I have to pick it up at the post office no earlier than two days from now, it also has the "Registered" box checked...and I'm not sure what that means. Even though I know clomid and nolv aren't class III drugs, I'm still a little freaked about the post office making me pick it up there. Should I be worried??? Or is it standard practice for international deliveries to be marked "registered" and require you to sign for it?
