Create straightforward checkout rules with a visual editor, start from one of three free templates, and preview sample conditions before enabling a rule.
MegalogicStudio Checkout Rule Guard is an independent plugin compatible with WooCommerce. It does not process payments, calculate shipping quotes, or enable payment methods that WooCommerce has made unavailable.
The free plugin includes its rule editor, all three templates, server-side rule evaluation, Classic Checkout and Checkout Blocks integrations, rule preview, and configuration conflict warnings. There are no paid feature locks, account requirements, telemetry, or advertising SDKs.
The subtotal condition uses the product subtotal before discounts, excluding tax and shipping, in the store currency. A coupon or tax can change the amount due without changing this configured subtotal value.
