Before you start
- The Premium plan.
- A clear sentence describing the rule: “orders shipping outside the UK must be at least £200.”
That sentence is worth writing down. The word and or or in it tells you the match type.
Steps
1. Install Nex Validator
Search Nex Validator in the Shopify App Store, or use the button below. Approve the permissions and the app appears in your admin under Apps. There is a free trial, and it works on every Shopify plan.
2. From the dashboard, choose Advanced Rules → Create Rule, and give it a title.
3. Add your Conditions — when the rule should apply.
4. Set the Match type: all conditions must match, or any.
5. Set the Action — the limit to apply when the rule matches.
6. Write the message, and add translations if you sell in several languages.
7. Set the status to active and save.
Verify it worked
| Cart | Expected |
|---|---|
| Matches conditions, breaks the limit | Blocked |
| Matches conditions, satisfies the limit | Completes |
| Does not match conditions | Completes, whatever the limit says |
| On the boundary | Behaves the way you intend |
The third row is the one people skip, and it is the one that catches an over-broad condition.
Keep them readable
Advanced rules accumulate. Give each a title stating the condition — Non-UK minimum £200, not Advanced rule 3 — and disable rules whose campaign has ended rather than leaving them to count against the 25-validation ceiling.
