If you want you can get a 14-day free trial period for all magazines and newspapers in your Kindle Store for Kindle Fire, Kindle devices, and Kindle reading apps.
So, you have to subscribe for that and even if you want to cancel in between the 14-day trial period you can do it and you would not be charged anything extra for that. But if case you do not cancel the subscription during the 14-day trial period, you would be deducted an amount of the current price of the magazines’ subscription price. This is done using the default 1-Click payment method. And one more thing is that only credit cards can be used for payment of subscriptions.
