Bonus Fill
Bonus fill is the classic same price, more product deal — a larger variant (the bonus size) is priced down to match the smaller base variant, so the customer pays the same amount and receives a bigger item. The BOGOify app equalizes the price in Shopify; physically fulfilling the larger item is the merchant's responsibility.
When to use it
Bonus fill works best for CPG products, supplements, beverages, and cosmetics where size variations already exist in your catalog. It resonates strongly with value-conscious repeat buyers.
Fulfillment note
BOGOify only adjusts the Shopify price. Sending the larger item to the customer — whether by over-filling, relabeling, or picking a separate SKU — is entirely your responsibility. Coordinate with your warehouse or 3PL before publishing this promotion. You must also pre-create the larger variant in Shopify before setting up the promotion here.
How to set it up
Before anything else, open your Shopify product editor and create the larger bonus variant (e.g. add a 32 oz variant to a product that currently only has a 16 oz option). Both variants must exist in Shopify.
Open BOGOify, click New offer, open More offer types and pick “Pay for the small, get the big”.
Choose the size customers pay for — the product and size they normally buy (e.g. 16 oz at $12.00).
Choose the bigger size they receive — it will be priced down to the base price (e.g. 32 oz).
Enter the advertised percentage (e.g. 20% more), check the live preview, then click Save and turn on.
Tips
- Coordinate with your warehouse or 3PL before publishing — the app sets the price, but you ship the bigger item.
- The advertised percentage is for your marketing copy. The BOGOify app sets the bonus variant's price equal to the base price, regardless of the actual size ratio.
- Works best for consumables and refillables where more for the same price is an easy, intuitive message for shoppers.
