title: With PayPal subscribe button, does the recurring billing continue indefinitely unless cancelled?
body: <p>I have created a <code>Subscribe</code> button using PayPal Standard button html code as below. The subscription billing cycle is monthly. For example, a user signs up for a Silver subscription at $150 per month or a Gold subscription at $200 per month.</p>
  
  <p><strong>Question</strong> : Will the monthly billing amount be automatically charged to the user every month <code>indefinitely</code> till user cancels the subscription, OR there is a maximum number of times it will be automatically charged?</p>
  
  <p>I could not find any documentation on this, so just wanted to be sure.</p>
