Buy One Get One - promotional offer providing a free or discounted additional item.

Why It Matters

BOGO offers feel like higher value than equivalent percentage discounts. 'Buy One Get One Free' (50% off) outperforms '50% off' in testing because customers focus on 'free.' BOGO also doubles units sold, which is valuable for building habits with consumables.

Practical Example

Scenario

A candle brand runs BOGO 50% on their $35 candles during holiday season.

Calculation

Regular month: 400 units × $35 = $14,000. BOGO month: 650 pairs × 2 × $35 × 0.75 = $34,125 (average effective price $26.25)

Result

Revenue increases 144% while moving 2.4x inventory. Margin compression (25%) is offset by volume and inventory clearance.

Pro Tips

  • 1BOGO Free on lower-priced items limits discount exposure
  • 2Require second item to be equal or lesser value to protect margin
  • 3Use BOGO to introduce customers to new products (free item is new SKU)
  • 4Stack BOGO with threshold for AOV protection ('BOGO on orders over $75')

Common Mistakes to Avoid

Letting customers BOGO your highest-margin hero products
Not limiting BOGO quantity (customer buys 10, gets 10 free)
Running BOGO too frequently—trains customers to wait for it

Frequently asked questions

BOGO Free is more attention-grabbing and psychologically stronger ('free' triggers stronger response). BOGO 50% protects margin better. For customer acquisition: BOGO Free. For regular promotions: BOGO 50%. Both beat equivalent percentage discounts in testing.

Limit per customer (2 BOGO pairs max). Require same or lower value on free item. Exclude sale items or specific collections. Set minimum quantity for full discount ('Buy 2 Get 1 Free' vs 'Buy 1 Get 1 Free'). Monitor for split orders from same customer.
