WWP + TM EPO Price Display Compatibility

WWP + TM EPO Price Display Compatibility

Fixes double-discounted wholesale prices on WooCommerce single product pages when WooCommerce Wholesale Pricing and TM Extra Product Options (EPO) are used together.

🧩 Problem

When using both plugins:

Wholesale discounts are applied globally by the Wholesale Pricing plugin. TM EPO recalculates prices for display and totals. This can cause double discounting, resulting in incorrect (lower-than-expected) prices on: Single product pages Variation selections TM EPO totals box ✅ Solution

This plugin ensures:

Wholesale pricing is applied once and consistently Prices displayed across WooCommerce and TM EPO are synchronized Correct price is used for: Product display Variation pricing AJAX requests TM EPO totals ⚙️ Features Prevents duplicate discount application Supports: Simple products Variable products Variations Handles all wholesale pricing levels: Group pricing Product tier pricing Product-level discounts Category pricing Global pricing Works with: Logged-in wholesale users Guest wholesale pricing (if enabled) Maintains proper “Sale” display with percentage savings Ensures idempotent pricing (same input → same output) 🔌 Requirements WordPress WooCommerce WooCommerce Wholesale Pricing plugin TM Extra Product Options plugin 📦 Installation
