title: A/B test subscription pricing and free trial effects
body: <p>We want to launch a new subscription product and be able to decide impact of free trial vs not and also couple different price options.</p>
  
  <p>For one IAP we would just create different skus and based of abtest bucket send the right sku. For subscription the IAP is auto renewed thus moving users from one bucket to another feels lot of friction.
  Also for understanding effects of free trial vs not doing it using one sku and in linear fashion seems to be better.</p>
  
  <p>What approaches have AD developers used for their subscription features?</p>
