Twelve in total, not twelve of each size

Suppose you print T-shirts and need at least 12 units of one design per order. Six Small plus six Medium should count as 12 units of that product. A product-level minimum combines its variants; a variant-level minimum applies only to the selected size or color.

Choose the level that matches your purchase condition. This is not a shared minimum across unrelated products or collections. A product minimum applies when the selected product is in the cart; it does not require every shopper to add that product.

Create and check a draft in M10 RuleSafe

1. Start a minimum product quantity draft and select the product.
2. Set the minimum to 12 and write a clear checkout message.
3. Save the draft. Saving alone does not change checkout.
4. Run the Safety Check, then try sample totals of 11 and 12.
5. Review the result before explicitly activating the checked version.
6. Verify your actual supported Online Store checkout before relying on the rule for customer orders.

What the sample test does and does not prove

The sample-cart simulator accepts a combined product total. Eleven is below this minimum; twelve meets this rule. It is not a live checkout or proof that every combination of discounts, other active rules, or storefront configuration has been tested.

Explain your purchase limit on your store before checkout. This version does not add a product-page quantity notice or a theme widget. If you need a minimum shared across different products, this rule is not the right fit.
