I pay for very few magazine subscriptions and yet I receive a ton every month. Here are a few links for free subscriptions. No credit card is needed. Take a survey (if necessary), give your address and voila. Make sure that when your subscription ends you mail the renewal card back saying you don’t want to renew. Otherwise, they will send out a lot of notices.
