About this plugin
Stop supported WooCommerce coupons from discounting protected products below the merchandise gross-margin floor you choose.
ProfitLatch Coupon Floor is designed for stores that already use WooCommerce core coupons and native Cost of Goods Sold, especially when coupon stacking can consume too much product margin.
What it does:
* Uses the current WooCommerce product price and native WooCommerce COGS.
* Limits WooCommerce core percent and fixed-product coupon discounts on each protected cart line.
* Tracks supported discounts already granted during the current totals calculation, so later supported coupons can use only the remaining safe discount capacity.
* Does not create another promotion engine.
* Does not automatically send store, order, product, coupon, or customer data to an external service.
* Is disabled by default until a store manager explicitly enables it.
Example:
* Product price: $100
* Native WooCommerce COGS: $80
* Required merchandise gross margin: 10%

If several supported coupons are applied, ProfitLatch Coupon Floor limits later coupon amounts so the configured product-level gross-margin floor is not crossed.

Compatibility and scope:
* Protects merchandise gross margin before shipping cost, payment-gateway fees, taxes, advertising costs, returns, and other order-level expenses.
* If a product has no usable COGS value, ProfitLatch Coupon Floor does not guess a cost and leaves the coupon calculation unchanged.
* Supports WooCommerce core percent and fixed-product coupons in this release.
* The hard-floor compatibility promise applies when all discounts affecting a protected line are supported core percent and/or fixed-product coupons.
* Fixed-cart coupons are deliberately left unchanged because WooCommerce has a remainder-allocation path that bypasses the discount filter used by this release.
* Third-party custom coupon types, dynamic-pricing engines, and mixed stacks that include unsupported discounts are outside the compatibility promise.

Why this is intentionally narrow:
Many discount plugins focus on creating promotions. ProfitLatch Coupon Floor does not replace them. Its purpose is to add a lightweight native-COGS safety check to WooCommerce core coupon calculations without introducing another pricing engine.
