Overlapping offers and priority: what the customer pays

The one rule that decides everything when several offers touch the same product.

6 min read

The Offers list is ordered by priority (arrows in the Priority column). That order decides which offer prices a product, on the product page, in the cart bar and at checkout. Two prices never stack on one item.

The rules

  • Unit-pricing offers (Volume, Mix & match) skip every product already covered by a higher Volume, Mix & match or Buy X get Y offer.
  • Add-ons (a free gift over a cart amount, a Frequently-bought-together discount on extras) apply on top of the winning price of the other lines and never block anything.
  • Frequently bought together appears alongside a pricing offer on the product page; store-wide offers never take the product-page slot from a product-specific offer.
  • The two variants of an A/B test count as one offer, ranked where the test is.
  • Overlaps are flagged with an “Overlap” chip in the list and a warning in the wizard.

Example

Offer 1: buy 2 boards, 20% off. Offer 2: any 2 boards for €1,000. Offer 3: free tote over €500. A cart with 2 boards and a tote gets 20% off the boards (offer 1 is higher), no set price (offer 2 skips products offer 1 covers), and the free tote (add-on). Move offer 2 above offer 1 and the set price wins instead.

Behind the scenes

Each MixMaxer discount is allowed to combine with the others; when an offer is saved or reordered, every discount receives a list of the products claimed by the offers above it and the discount Function skips those lines. This is why saving one offer re-syncs all of them.

Common problems

I want both a volume tier and a set price on the same product.

Not possible on the same item, by design. Put the set price on a collection and the volume tier on individual products outside it, or decide by priority.

A discount code stops the offer.

A product-level code stacks with the offer only if the code allows combining with product discounts; otherwise Shopify keeps the larger saving. Order-level and shipping codes combine when the offer's “Combine with discount codes” option is on (see “Combining with discount codes”).
