For example, a sports-related service might lower the subscription 33 price halfway through the sport's season.</li> 34 <li><strong>Free Trials</strong>—Content providers can 35 offer free trial periods for all kinds of subscriptions, including 36 seasonal subscriptions. If a user cancels the subscription in the trial 37 period, they pay nothing. If they do not cancel by the end of the 38 trial period, the subscription automatically converts to a paid 39 subscription.</li> 40 <li><strong>Subscription Upgrade/Downgrade</strong>—A user can 41 subscribe to a higher or lower tier of subscription while their current 42 subscription is active.
