Limit Once

Limit Once is a Shopify App that allows merchants to set items to one-per-customer and block repeat orders. It helps in selling selected products only once per customer, useful for free samples, first-time offers, limited drops, or products not meant for repeat purchases. The app checks repeat purchase attempts during checkout, including guest and express checkout, and provides a clear message to block them. Merchants can enable or disable the rule for each product at any time.
