5 Effective “Buy One, Get One Free” Promotions for Your Online Store
Five BOGO structures that increase basket size, clear stock and build loyalty — plus how to decide which products are a good fit and how to run them without hurting your margins.
Key takeaways
- BOGO promotions drive volume, clear stock and add urgency — but only when structured correctly.
- Five reliable formats: 50% off the second item, category cross-sell, free samples, 3-for-2, and accessory discounts.
- Best applied to replenishable, complementary or paired products with healthy margins.
- Timebox the offer, communicate clearly and measure the impact against your average order value.
What a BOGO promotion actually is
A BOGO promotion gives a customer a free or discounted item when they buy another product. The most common formats are buy one get one free, buy one get 50% off, buy two get one free, and three for the price of two. Retailers use them to drive volume, spotlight categories and clear slow stock. Customers respond because the offer feels like clear, tangible value.
Five formats worth testing
Not every BOGO is the same. Each format works best for different products.
- Buy one, get one 50% off — protects margins better than a full freebie; good for bestsellers.
- Buy from category A, get from category B free — great for themed campaigns and cross-selling.
- Buy one, get free samples — introduce customers to more of your range.
- Buy three for the price of two — increases volume with a strong sense of saving.
- Buy X, get % off Y — push accessories and complementary products alongside a main item.
Is BOGO right for your products?
BOGO campaigns work best on the right kinds of products. Look for items that customers replenish (household essentials, personal care), pair naturally (shirts and pants, shampoo and conditioner), or come in sets (socks, candles, notebooks). Aim for products with healthy margins so the promotion stays profitable.
How to run a BOGO campaign well
Time the offer to a genuine window — payday, holidays, back-to-school. Communicate the rules clearly across banners, product labels and email. Focus on a small number of strong offers rather than a wall of overlapping promos. Track sales, margins and average order value throughout the campaign, and adjust for the next round.
