A Buy X Get X is a threshold-based mechanic, where shopper participation depends on meeting a purchase condition.
Key considerations:
Redemption – not all shoppers will buy enough units to trigger the offer
Effective price per unit – driven by how the mechanic translates into a reduced price across all units
Expected volume uplift – depends on how compelling and achievable the offer is
Coverage – broader reach increases impact but also cost
Funding approach (OI vs Scan) – determines how costs are applied
Merchandising support – helps communicate the mechanic clearly
Cannibalisation within your range – increased demand on some SKUs may reduce sales of others
A strong Buy X Get X balances shopper value, participation, and total investment, while considering the net impact across your product range.
