Please note that this mode determines sameness based only on the information stored within the cart. If two items differ in specification but that difference is not preserved in the cart data, they may be treated as identical and aggregated across lines. If you need to avoid this behavior, choose “Per line.” In this mode, even completely identical configurations will not be merged if they were added as separate requests. In such cases, customers may need to adjust quantities directly within the cart to receive bulk pricing.

For example, when purchases involve uploaded files or dynamically generated data, whether identifying information is stored in the cart depends entirely on the implementation of your custom plugins. Because results may vary depending on your site configuration, we recommend testing in advance and selecting the aggregation method that best fits your setup.

All calculations occur naturally within WooCommerce without adding complex interfaces or affecting the storefront’s appearance or usability. The plugin works seamlessly with both the Classic product template and the WooCommerce Blocks-based product layout, ensuring consistent behavior regardless of your storefront configuration.
