One of the most common questions on Shopify forums is how to limit customers to one purchase of a specific product. Native Shopify tools fall short, but there is a straightforward solution.
Some products should not be in the same cart due to shipping, business model, or operational constraints.
Standard order limits only apply to a single transaction, allowing customers to purchase again after completing an order. Customer purchase limits track buyer history across all orders.
New exclusions feature allows merchants to apply broad rules while carving out exceptions for specific products or customers.
Weight-based limits control purchases by total item weight rather than quantity or price, improving fulfillment efficiency.
Weight-based order limits help merchants maintain control over shipping expenses by setting minimum or maximum weight thresholds.
