Well, looks like I'm a huge idiot.  Apparently some of the magnets last month got sent out without being sealed.  Serves me right for thinking I could accomplish anything useful the afternoon after my divorce hearing.  Anyway, if you didn't get a magnet that you were due, let me know and I'll try to get some more and resend them.  I have no idea how many people were affected, but regardless I have no good explanation other than a huge brain fart.
