I got mine late last week, but I too get it first class mail. Though sometimes, some club members here get theirs the same time as I do, and sometimes not.
Magazines move in mysterious ways at times in the US Postal system. It is not as "sort of consistent" as happens with 1st class mail.
If you do not get yours by June 15th, then I'd say it's "Missing". Until then, it's likely working its way thru the US Mail system. Your copy is not really even "late" yet.....
