  -This example uses the  https://github.com/killbill/killbill-docs/blob/1a945188c0ef53a3c7f797b4890514d35c09c46f/catalogs/discount-and-evergreen.xml[Discount and Evergreen] catalog. In this case, the `standard-monthly` plan has a `DISCOUNT` phase of `3` months (with a monthly charge of `$4.95`) followed by an `EVERGREEN` phase with a monthly recurring charge of `$24.95`. So, users will be charged `$4.95` (discount price) for the first `3` months. After that, they will be charged a recurring price of `$24.95` monthly in perpetuity.

  Another important section in the catalog is the https://docs.killbill.io/latest/userguide_subscription.html#_billing_alignment_rules[Billing Alignment Rules] section. 
  
  Brief summary about the Billing Alignment Rules:
  
  * The _Billing Alignment Rules_ section specifies whether the user will be billed at the account level, subscription level or subscription bundle level. 
  * If the catalog specifies `ACCOUNT` billing alignment, all the subscriptions belonging to the account are aligned and invoiced with the _Bill Cycle Day (BCD)_ specified while creating an account. 
  * If the catalog specifies `SUBSCRIPTION` billing alignment, each subscription will be invoiced as per its bill date.
  * If the catalog specifies `BUNDLE` billing alignment, all the subscriptions within a bundle are aligned and invoiced on the same day. 
  
  This section provides examples of catalogs with different billing alignment rules.
  
negative.code: When `SUBSCRIPTION` billing alignment is specified in the catalog, each subscription is invoiced separately as per its bill date. 
  
  [NOTE]
  *Note:* `SUBSCRIPTION` billing alignment applies even for subscriptions that are part of the same subscription bundle. So, if a subscription bundle consists of a base plan and an add-on plan, the add-on plan is invoiced as per its own date and is NOT aligned with the base subscription billing date.
