Custom Discount examples

Each example below is a complete setup. Read the goal, copy the settings, done.

The first group needs nothing but the discount page. The second group reads prices from a metafield — if you have not set one up, start with Set up the price metafield. In the third group, 14 and 15 add up a number from that metafield and 16 needs no metafield.

No metafield needed

1. A plain percentage off a collection

Goal. 20% off everything in Summer Sale.

• One cart group named Summer range, one condition: Specific collections, and pick Summer Sale.
• One product offer, value Percentage off, 20, applied to Summer range.

Nothing else. This is the simplest thing Custom Discount does, and it needs no product data.

2. A fixed amount off each item

Goal. £5 off every mug, however many they buy.

• One cart group Mugs, condition Specific collections, and pick your Mugs collection.
• One product offer, value Fixed amount off per item, 5, applied to Mugs.

Fixed amount off per item takes £5 off each unit. Fixed amount off would take £5 off the group once, no matter the quantity. Pick deliberately.

3. Free shipping over a threshold

Goal. Free delivery once the basket passes £50.

• One shipping offer, value Free shipping.
• On that offer, a requirement: group All items, measure Subtotal, is greater than or equal to 50.

No product offer at all. A Custom Discount can hold only a shipping offer.

4. A product discount and free shipping together

Goal. 15% off outerwear, and free delivery when they buy some.

• Cart group Outerwear, condition Specific collections, and pick Coats and Jackets.
• Product offer: Percentage off 15, applied to Outerwear.
• Shipping offer: Free shipping, with a requirement on group Outerwear, measure Quantity, is greater than or equal to 1.

One discount, one code if you want one, both effects.

5. Discount the whole order, not the items

Goal. £10 off the order when they spend £100.

• One order offer, value Fixed amount off, 10.
• Requirement on the offer: group All items, measure Subtotal, is greater than or equal to 100.

An order offer discounts the order total. A product offer discounts the items. Use an order offer when the amount should not be split across lines.

6. Against the compare-at price

Goal. Show 30% off the original price on items that have one.

• One product offer, value Percentage off compare-at price, 30.

The saving is worked out from the compare-at price rather than the selling price. Products without a compare-at price, or with one below the current price, are skipped.

Prices from your own data

Everything below needs the metafield set up first. These examples use custom.volume_pricing and write amounts as plain prices with "unit": "major".

7. Wholesale case pricing

Goal. Every SKU has its own price at 6 and at 12.

On every variant:

{ "v": 1, "unit": "major", "qty6": 8.50, "qty12": 7.50 }

• Turn on Read prices from a variant metafield. Namespace custom, key volume_pricing.
• One product offer, value Price from product data, field qty, meaning Fixed price for the item, Tiered by line quantity on, applied to All items.

Six mugs cost 8.50 each. Twelve cost 7.50. A SKU with no price data is left alone. One discount covers the whole catalogue, and you change prices in the data, never in the discount.

8. The same, with a floor so nothing sells at a loss

Goal. A deep tier must never take an item below cost.

{ "v": 1, "unit": "major", "qty6": 8.50, "qty12": 7.50, "floor": 7.00 }

Same offer as above, and name floor in the offer’s Floor field.

Precaución

Every variant that offer can reach then needs a usable floor. A variant without one gets no discount at all — the limit is never dropped quietly.

9. Contract pricing for one customer group

Goal. Trade accounts pay a different price from everyone else.

{ "v": 1, "unit": "major", "retail": 8.50, "contract": 6.75 }

• Cart group Trade, condition Customer tags · is one of · contract.
• Product offer A: Price from product data, field retail, applied to All items.
• Product offer B: Price from product data, field contract, applied to Trade.
• Set When offers overlap to Apply the discount that saves the most.

Two prices per variant, one discount, and the customer’s tag decides.

10. Case packs only, chosen by a number in your data

Goal. 10% off SKUs that ship as a case of 12, without keeping a product list.

{ "v": 1, "pack": 12 }

• Cart group Case packs, condition Price data number, field name pack, is greater than or equal to 6.
• Product offer: Percentage off 10, applied to Case packs.

Add a pack number to a new SKU and it joins the discount on its own. Nothing else in the cart is touched.

11. Everything except the case packs

Goal. The complement of example 10.

Take the same group and set its Match to none. That selects every item the group does not match, including items with no price data at all. Point a second offer at it.

12. Clearing a season

Goal. 25% off last season, and the discount never needs editing again.

{ "v": 1, "season": "ss26" }

• Cart group Last season, condition Price data field, field name season, is one of ss26.
• Product offer: Percentage off 25, applied to Last season.

When the season turns over you change the data, not the discount.

13. A percentage that differs per product

Goal. Each supplier agreed a different discount rate.

{ "v": 1, "rate": 12.5 }

• Product offer, value Price from product data, field rate, meaning Percentage off.

A percentage is read exactly as written, so 12.5 is 12.5%. It is not affected by the unit setting. A variant with no rate gets nothing.

Weight and repeating deals

14. A deal once the cart holds 1 kg, any mix of bags

Goal. 10% off coffee once the cart holds at least 1 kg — four 250 g bags, two 500 g bags or any other mix.

• On each coffee variant, add the weight in grams to its price data: {"v":1,"g":250} on the 250 g bag, {"v":1,"g":1000} on the 1 kg bag, and so on.
• Turn on Read prices from a variant metafield and enter the metafield.
• One cart group Weighed coffee matching all of: Specific collections is one of Coffee, and Price data number g is greater than or equal to 1. The second condition keeps a mug or a grinder from the same collection out of the deal.
• One product offer, Percentage off 10, applied to Weighed coffee, with a requirement: Weighed coffee, Price data total, number name g, is greater than or equal to 1000.

950 g gets nothing; 1000 g or more gets 10% on every bag.

15. Money off for every full kilo

Goal. 5 off for every full kilo of coffee, at most three times.

• Set up as in example 14, but use Fixed amount off 5.
• Tick Repeat for every full step, choose the requirement in Step, and set Max times to 3.

1 kg gets 5 off, 2,400 g gets 10 off, 5 kg gets 15 off. The amount is shared across the coffee in the cart.

16. Money off for every 500 spent

Goal. 50 off the order for every full 500 spent. No metafield needed.

• One order offer, Fixed amount off 50, with a requirement: All items, Subtotal, is greater than or equal to 500.
• Tick Repeat for every full step and choose that requirement in Step.

A 1,250 order gets 100 off; a 499 order gets nothing.

Before you launch any of these

• Use Check a product on the discount page. It reads a real variant and shows what would happen, or the reason nothing would.
• Use Test mode to put the discount live for one signed-in customer only, check a real cart, then turn it off.
