A subscription is an automatic recurring charge for a product or service.

A customer agrees to be billed on a recurring basis for a specific amount to receive a product in the mail or to gain access to a service.

For example, customer can subscribe to 1 bag of coffee every week.

It will be delivered to them weekly and they will get billed automatically on a recurring basis.

By subscribing, the customer can get a discount price for being a repeat customer.

For example, if they buy the bag of coffee as a one-time purchase, it costs $12.

However if they choose to "subscribe & save" the bag of coffee as a subscription costs only $10.

Subscriptions help store owners sell more with repeat orders.
