The nine limits
| Scope | Minimum | Maximum |
|---|---|---|
| Cart quantity | Minimum cart quantity | Maximum cart quantity |
| Cart value | Minimum order amount | Maximum order amount |
| Product quantity | Minimum product quantity | Maximum product quantity |
| Collection quantity | Minimum collection quantity | Maximum collection quantity |
| Bulk (metafield) | Product bulk limit — Premium |
Picking the right scope
Ask what you are actually protecting.
| You want to | Use |
|---|---|
| Stop unprofitable small orders | Minimum order amount |
| Make orders worth packing and shipping | Minimum cart quantity |
| Stop resellers clearing a drop | Maximum product quantity |
| Ration a whole limited range | Maximum collection quantity |
| Sell in cases of 6, 12, 24 | Product bulk limit |
Amount and quantity are the pair people most often mix up. A £200 minimum and a 10-item minimum behave completely differently on a store with a wide price range.
Minimums and maximums are different jobs
They share a form, and nothing else.
Minimums exist to protect margin. The risk is setting them too high and losing orders you would have wanted.
Maximums exist to protect stock and fairness. The risk is setting them too low and blocking your best customers.
Combining limits
One rule can hold several limits. A cart minimum and a per-product maximum in the same rule means the customer must clear the cart minimum and stay under the product cap.
If any limit in the rule fails, checkout is blocked and your message is shown.
For limits that should only apply in some situations — a country, a customer group, a date range — see Advanced rules.
