Now of course, I didn't give Good Housekeeping my credit card number when I entered the sweepstake, but I've heard horror stories where people have had their credit reports damaged by magazines trying to collect on subscriptions that they never ordered, so I am far from happy with this development. I canceled the "subscription" through their online site and sent them a complaint in an email. Automatically signing me up for a subscription that I did not agree to receive is a pretty clear violation of the no consideration aspect of sweepstakes laws. I have asked Good Housekeeping for an explanation, but so far I've only received a form letter in response.
I'll let you know if I receive a more thorough response from Good Housekeeping. However, you should be on alert for subscription emails if you register for this sweepstake, and be sure to unsubscribe if you don't want to receive the magazine.
