RuffRuff Order Limits vs UR

RuffRuff Order Limits helps you manage quantity, order value, weight, customer, product combination, payment, shipping and access rules on Shopify. Set minimums, maximums and multiples, limit cumulative quantity or spend across orders, and set quantity limits by customer group. Enable VIP-only sales, prevent pre-orders from mixing with regular items, hide payment or delivery options, and password-protect pages. Target products, collections or variants without coding or changing your theme code.

This app prevents duplicate purchases by enforcing a one item per customer rule at both cart and checkout. It is ideal for limited stock items, exclusive products, or campaigns where fairness matters. By displaying clear error messages on product and cart pages, customers immediately understand purchase restrictions, reducing confusion and support inquiries. Integration with the Cart and Checkout Validation API ensures reliable enforcement without disrupting the shopping experience.
