Discounts

Discount functions create app discounts in your Shopify store. They appear under Discounts in Shopify admin, and customers see the function’s title at checkout next to the discount.

Choosing products

Most actions have an Eligible products choice: All products or Only products that match…, where you build a filter such as Product tags has any of summer or pick products and collections. Bundles, mixed discounts and gifts always ask which products they use.

Exclude items already on sale

Product discounts can skip sale items. Tick Exclude items already on sale and items with a compare-at price above their price neither count toward the discount nor get discounted again.

Message

Message shown to customers (optional) appears next to the discount at checkout. {value} is replaced with the discount: {value} off with our spring sale becomes 20% off with our spring sale. For fixed amounts, {value} is the number without a currency symbol, so write ${value} off if you want one.

A few things to know

• Buy X get Y gives the cheapest qualifying items first. If the “get” items come from the same products as the “buy” items, each set needs buy + get units.
• Quantity breaks check each cart line separately. An amount-off tier takes the amount off each unit.
• Tiers — the highest tier the cart reaches applies.
• Tiered gifts — Shopify Functions can’t add products to the cart. The gift is discounted once the customer adds it, so tell customers about the gift on your store. Exclude gift products from the products that count toward the tier.
• Order discounts — when several order-level discounts from one function apply, Shopify keeps the largest. Product discounts all apply.
• A shipping discount can’t be in the same function as product or order discounts — create one function for each.

Discount settings

The Discount settings card in the sidebar controls how Shopify applies the discount.

• Method — Automatic discount applies by itself when the conditions match. Discount code applies only when the customer enters the code you set (letters, numbers, dashes and underscores; it’s saved in capitals).
• Can combine with — tick Order discounts, Product discounts and/or Shipping discounts to let this discount stack with others of those kinds. New discounts start with the defaults from Settings.

Note: Changes to the title, discount settings or dates of a live discount reach Shopify when you click Save & publish.

Limits

• Shopify allows up to 25 active app discounts per store, and free and discounted shipping functions count toward them.
• Each function can have up to 20 actions; tiered actions up to 20 tiers; bundles up to 10 items.

Ideas
