Here is a response one of my friends got:
Thank you for your message.
Dear Valued Customer,
In the past, certain websites have posted seasonal promotion advertising
from Wal-Mart -- and many other retailers -- without authorization. Because
these websites have not respected copyright protections and other laws, we have
reminded them of their obligations under the law. Customers will be able to
find the Black Friday Wal-Mart specials on walmart.com beginning Nov.19th.
Thank you,
Wal-Mart Customer Relations
