A plan includes pricing and billing cycle information that defines the amount and frequency of charge for a subscription. You can also define a fixed plan, such as a $5 basic plan or a volume- or graduated-based plan with pricing tiers based on the quantity purchased. For more information, see Subscriptions Overview.",
