How offers combine

When a cart qualifies for more than one of your offers, the shopper gets the one that saves them more. Offers do not stack unless you allow it.

The default: the best single offer

Each offer is set up in Shopify so that it does not combine with your other offers. If a cart qualifies for, say, a buy X get Y offer and a spend threshold, Shopify works out which one saves the shopper more and applies that one. The shopper never pays more than they would with either offer alone.

Let an offer combine

• Open the offer and find Combining with other offers.
• Turn on Can combine with other offers.
• Click Save.

Do the same on every offer that should stack. Two offers apply together only when both have it turned on.

Things to know

• A product gets at most one product discount, even when offers combine. If two offers discount the same product, the shopper gets the one that saves more on it.
• Offers of the same kind, for example two volume discounts on different products, can both apply in the same cart. On the same product, the offer with the higher priority wins.
• Spend thresholds and gifts with a minimum spend count the cart's full price, before other discounts, as Shopify's own minimums do. A shopper who also gets a buy X get Y offer still counts the free item at its full price toward the minimum.
• The setting also decides whether an offer combines with your other Shopify discounts, such as discount codes. An offer with it off does not combine with other product or order discounts. Free shipping discounts always combine.
