SEEKING education related newsletters, circulars, magazines (for Maryland)

Need some decent newsletters to advertise teacher related events.....

Hello.

I represent a Columbia, MD based book warehouse.  We offer huge discounts
to
the general public, but also offer an additional discount for teachers,
and
we stock alot of education related materials.  We would like to let
teachers
here in the Maryland area to know about an upcoming teacher gathering we
will be having on President's day in February.  Can anyone recommend any
newsletters where we might be able to place an advertisement?

I welcome your assistance.  If you have any questions about this event -
or
suggestions about newsletters.... Please respond to this post.  Check out
our website for more info about who we are, and the types nof books we
carry.

Thank you very much.
