Limit Once

Limit Once is an app that allows ecommerce 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 merchants do not want shoppers to buy repeatedly. The app checks repeat purchase attempts during checkout, including guest checkout and express checkout, and blocks them with a clear message. Merchants can enable or disable the rule for each product anytime.
