First purchase versus repeat purchase
A customer with no recorded purchase of a product is not capped by the cumulative threshold on their first purchase. Add a cart quantity rule to control the first order. Once history exists, each product is checked using recorded quantity plus current cart quantity. Exceeding the threshold blocks the purchase. Variants of one product count together; different products do not share one allowance.Identity and record source
- Customers must sign in to buy products covered by cumulative rules.
- Newly created orders linked to a customer record non-subscription product quantities.
- Orders from before the app was installed are not automatically imported.
- Orders already recorded by the app before a rule was enabled may affect later checks. Activating a rule does not reset history.
- Records update after order creation processing. Do not assume immediate synchronization between consecutive or concurrent checkouts.
Product scope
A cumulative rule supports at most 250 products. For All products, the shop’s total product count must also be within 250. Larger stores should choose Specific products within this limit. Collections are not supported. When changing the product selection, check existing purchase records as well.Recommended sample setup
- A cart quantity rule for the sample: individual calculation, maximum
1. - A cumulative rule for the same sample: threshold

Identity is based on the customer account the store recognizes. This feature does not promise to identify the same person across different accounts.
