Neiman Marcus sent a very small flier in the mail that said they intended to sell my credit card information. It was a very nondescript mailer with incredibly small print. At the end of the mailer they gave an address that I could send a letter to if I did not want my information sold. They gave no envelope, no stamp and this flier looked like junk mail - easily missed. Everyone should know that they intend to sell your information if you have a credit card with them.
