WooCommerce Dynamic Multi-Buy Offers

I need my WooCommerce store to recognise “multi-buy” promotions such as 5 for 100, 4 for 100, 3 for 100, 2 for 50 and any similar deal I create in the future. The discount must calculate automatically at checkout—e.g. if two qualifying items that normally cost 5 each are in the cart, the total for those two lines should instantly drop to 5, not 10.

I’m happy for you to mix a solid, well-maintained plug-in with custom PHP/JS so long as the final solution is lightweight, update-safe and easy for me to extend from the WordPress admin (no hard-coding every new offer). Deals will apply store-wide; there are no user-role or minimum-cart restrictions to worry about.

Please be ready to start right away and show briefly which plug-in you’d pair with your custom logic—or outline a clean bespoke route if you have one in mind. The finished work should:

• let me add, edit or remove “X for Y” offers without touching code
• display the correct discounted totals on the cart and checkout pages in real time
• stay compatible with future WooCommerce core updates

If you can deliver this, I’m keen to get moving today.
