Mark items as “one per customer.” Limit Once blocks repeat orders at checkout.
Limit Once prevents second-time purchases of chosen products. Select the items to cap, and the app enforces a “one per customer” rule during checkout—including express options—so repeat attempts are declined with a clear message. Setup takes minutes in Shopify, and you can turn the rule on or off per product whenever you need.
