A Post-Purchase promotion is an engagement-led mechanic, where the shopper benefit is not delivered at the shelf, but after purchase.
Key considerations:
Shopper participation – not all buyers will redeem or engage
Expected volume impact – driven by attractiveness and ease of participation
Coverage – which stores or channels the promotion applies to
Funding structure – whether the retailer is involved financially or not
Execution complexity – redemption, fulfilment, or entry mechanics
Cannibalisation within your range – increased demand for one SKU may reduce others
A strong Post-Purchase promotion drives incremental volume and engagement, while managing how and where the cost is incurred.
