“Which of our discounts block each other?”
Combinations checks every pair of discounts that can be live at the same time, and says how to fix each pair that blocks.
Get notified: Coming soonThe issues, by kind
One line of totals, then a button per kind with its count. Each row names the pair (“SUMMER20 and Buy three, get 30 percent off”) in one line; Details has the full sentence, how to fix it, links to the discounts in Shopify and the test carts that ran into it.
| Kind | What it means | How to fix it |
|---|---|---|
| In your test carts | A saved test cart lost a discount to the other one of a pair. | As for the pair’s kind below. |
| One-sided | Only one of the two is set to combine with the other’s kind, so neither stacks. | Turn on the missing setting in the one that blocks, or turn it off in the other, so its settings say what happens. |
| Same items | Two product discounts cover the same items; only one applies per item. | Give them different items; otherwise the bigger one applies. |
| Scheduled | A scheduled discount will be live together with one it can’t combine with. | Let them combine, or move the dates. |
| Ended codes | A code that ended in the last 30 days, after it had been used. | Extend it, or stop advertising it. |
Blocking discounts groups the one-sided pairs by the discount that’s set not to combine, most pairs first, so one setting can fix a whole row.
The matrix (Pro and Business)
Every active or scheduled discount against every other (up to 30): Yes (they combine), One side, Same items, No (neither combines, often on purpose) and Other dates (never live together). The joints view draws the same as coupons around one discount; select another to put it in the middle.
Good to know
- Only pairs that can be live at the same time count: expired discounts are skipped.
- Discounts from apps can’t be checked for same items, because the app decides their items. They’re listed as not checked.
One pair, explained on a real cart: two discounts that can’t be used together.

Read the answer
The price X-ray shows each layer, and every code that wasn't applied gets a sentence saying why. Save it as a test cart to have it checked again.
