Why WooCommerce Doesn’t Offer BOGO
WooCommerce has a simple discount and coupon system, but it lacks advanced promotional features like BOGO. To create such discounts, you need to write custom PHP code for full control.

Add Buy 2 Get 1 Free Offer Using Custom Code
Since WooCommerce doesn’t provide a built-in BOGO feature, you can add the following PHP code to your theme’s functions.php file. This method ensures that:
- The discount applies only when a total of 3 or more items (including quantities) are in the cart.
- The cheapest product is free.

add_action('woocommerce_cart_calculate_fees', 'twapply_buy_2_get_1_discount'); function twapply_buy_2_get_1_discount() { if (is_admin() && !defined('DOING_AJAX')) { return; } $cart = WC()->cart; $cart_items = $cart->get_cart(); $total_quantity = 0; $prices = []; // Loop through cart items to count total quantity and store prices foreach ($cart_items as $cart_item_key => $cart_item) { $quantity = $cart_item['quantity']; $price = $cart_item['data']->get_price(); // Add each product's quantity to the total $total_quantity += $quantity; // Store price as many times as quantity for ($i = 0; $i < $quantity; $i++) { $prices[] = $price; } } // Apply discount only if there are at least 3 items in the cart if ($total_quantity >= 3) { asort($prices); // Sort prices in ascending order $lowest_price = reset($prices); // Get the lowest price // Apply discount if ($lowest_price > 0) { $cart->add_fee(__('Buy 2 Get 1 Free Discount', 'woocommerce'), -$lowest_price, true); } } } |
How This Works:
- ✅ Counts total product quantity instead of just product count.
- ✅ Sorts all items by price (considering quantities) and picks the lowest-priced one.
- ✅ Applies a discount equal to the cheapest product’s price if at least 3 total items are in the cart.
