I wouldn't even trust these numbers as "real".
I live in Allentown, PA.
I subscribe to the Morning Call newspaper for Saturday and Sunday.
They give me Thursday and Friday for free.
Sometimes, I get Monday for free also.
Somehow, I'd bet that those free ones count toward their circulation, even though I don't subscribe to them.
Those copies have to be reported separately, so the advertisers know how many copies are distributed that way.
