How does Subscribe & Save actually work commercially?

Subscribe & Save lets a customer turn a purchase into a recurring delivery in exchange for a discount, which the brand funds. Each month’s subscriber orders ship automatically, and the discount typically deepens for customers who stack several subscriptions.

The economics are a lifetime-value trade: you give away margin on every subscription order to keep a customer whose acquisition you have already paid for. For replenishable healthcare products, vitamins, lens care, emollients, oral care, the maths usually favours the subscription heavily.

The strategic prize is the baseline. A growing subscriber base is demand that arrives every month regardless of rank, promotions or competitors, which steadies the flywheel and de-risks everything else you do.
