There was no admission charge when Hashem gave the Torah at Har Sinai. The Medrash explains that Hashem chose this Midbar site to teach us that the Torah is available free to all of us.
Thus in honor of this event we will sent free samples of some Torah publications to those who write in a mailing address.
Now may be a good time for a gem of Torah study.
