Choose which products the limit applies to
Under Select products to limit, choose Apply this limit based on:- All products — the rule applies to your entire catalog.
- Specific products — pick individual products or variants using the browse dialog. You can search by product name or SKU.
- Exclusions — the rule applies to all products except the ones you select.
Product selection is capped for very large selections. If you need to
select more products than the picker allows, contact support and we’ll
raise the cap for your store.
Limit conditions
The minimum is a required field. If you only want a maximum, set the
minimum to
1 — every order trivially satisfies it.Sell in multiples
Enable Sell products in multiples when products must be bought in packs or combos — for example, wine sold in multiples of 6. The Multiple value must be at least 2. Customers see a message when their quantity isn’t a valid multiple, using the{{multiple}}
message variable:

Cap each variant separately (sizes, colors)
Count each size or color on its own with per-variant limits.
Enable Apply to each variant. With a maximum of 5, a customer can
buy 5 of the Small and 5 of the Medium — each variant is counted on
its own. Leave it off to count all variants of the product together.

Troubleshooting
The limit doesn't apply at all
The limit doesn't apply at all
- Check the limit’s status toggle in the Limits list — it must be Active, not Inactive or Scheduled (a future start date delays activation; times are GMT+0).
- If the limit targets customer tags, remember tags only resolve for logged-in customers.
- Verify the theme extension is enabled — see the dashboard’s Active App Block(s) card and Installation & theme setup.
The message shows, but customers can still check out
The message shows, but customers can still check out
- Settings → Rule settings may be set to Allows customer to purchase even if limits are not met — switch to the Blocks option.
- The checkout validation for product limits may be missing. Open the limit — if you see an Enable Checkout Rule button at the top, click it and add the Yuko Product Limit validation in Shopify’s checkout settings.
Limits behave oddly on products with many variants
Limits behave oddly on products with many variants
Check the Apply to each variant toggle — with it on, each variant
has its own count; with it off, all variants are summed. The wrong
setting here is the most common cause of “the max is being hit too
early / too late” reports.
Two limits cover the same product
Two limits cover the same product
All active limits are enforced together, so the strictest combination
wins. If a product is in both a product limit and an overlapping rule,
review both and deactivate the one you don’t need.
Refine the rule
Every limit also supports customer tag and country targeting, scheduling, and custom messages with translations.Need help?
