You can check this behavior on our demo product → [Demo] Flowers — Multiples of 4 Only
Use this when you want to sell products only in specific bundle units — for example, products like bouquets where the quantity itself is meaningful. Customers can select quantities starting from 1 on the product page, but only multiples of 4 are accepted per order.
When customers add the eligible items to their cart (or attempt to purchase), the following behavior applies based on quantity:
Multiples of 4 (4, 8, 12, 16, … items) → Allowed
Non-multiples of 4 (1, 2, 3, 5, … items) → Not allowed
Field | Value |
|---|---|
① Title | Enter any title |
② Limit details > Minimum quantity | 4 |
② Limit details > Maximum quantity | (Not set) |
② Limit details > Increment | 4 |
② Limit details > Applicability | Variant |
③ Eligible items | Set the products you want to restrict |
④ Product message | Enter any message |
⑤ Alert message > Display timing | Checkout only |
⑤ Alert message > Minimum quantity message | Enter any message |
⑤ Alert message > Increment message | Enter any message |
Setting Increment to 4 displays an error at checkout when customers attempt to purchase a quantity that is not a multiple of 4.
The restriction check may not work correctly on the cart page. We recommend setting the alert message Display timing to Checkout only.
Using
{{increment}}in the Increment message dynamically displays the increment value (4) within the error message.
