What is subscribe-and-save?

Subscribe-and-save (also called the replenishment model) is a subscription business model where merchants offer the same products on a recurring basis, often for a discount on product pricing and/or shipping. 

Typically, this type of subscription is geared toward daily consumable products, such as dog food and dog treats, household goods, coffee, personal care items like diapers and toothpaste, and certain food items or snacks. In addition to the discounted nature of the product, replenishment subscriptions are also appealing for customers for their convenience, delivering commodity items on a recurring basis. 

Replenishment subscription options can be offered alongside one-time purchase options (as seen in Amazon’s product detail pages), or offered as physical subscription boxes.
