Really. I've almost always received it in the third week of the month.
Some times sooner but rarely for me.
It's only been basically ten days. For me, it is usually more like 12
to 15 mailing days.
Some people think that the checks are mailed on the 10th but that
is not true. Checks are processed on or about the 10th of
the month. This means they have to download the payments, and
make the checks ready for mailing. I think this might take them a
few days or more, depending on the number of checks. Also, even
before that, I am sure they scrutinize for cheats, etc.
So anyway, if you ever get your check before the third week in the
month, that is great. However, usually it is in the third week.
