Topic summary
Goal: enforce a fixed item count for a subscription (e.g., a build‑your‑own 6‑pack) so customers can’t check out with fewer items after reaching the cart/checkout.
Platform context:
- Subscriptions use selling plans via the Cart API; items with the same selling plan allocation merge into one subscription contract.
- There’s no native subscription feature to require a specific item quantity at checkout, and customers can remove items in cart.
Explored options:
- Shopify Bundles were suggested, but they don’t support selling plans (and are limited to Online Store, not POS).
- Cart transformation app extensions also don’t support selling plans, so they can’t enforce the rule there.
Third‑party app lead:
- Juo Subscriptions claims the ability to set minimum and maximum products in a subscription box (vendor offered to share screenshots).
Status and open questions:
- No confirmed native Shopify solution; platform limitations persist around selling plans in bundles and cart transforms.
- A potential resolution may be via a third‑party subscription app, but effectiveness and integration details remain unverified by the OP.
