I wish to set up a specific discount on a particular variable products, if customer buys one product they get the another(same) on 50% discount(Buy one get another for 50% off). I’ve tried many discount plugins buy the closest that I have found are:
Pricing Deals for WooCommerce
WooCommerce All Discounts Lite
- WooCommerce Extended Coupon Features
By using these plugins I was able to setup discount on subtotal or discount on a each product but not exactly what I am looking for(Buy 1 get 1 off). There are other pro plugins I don’t want to go for it.
Is it possible to achieve without purchasing a plugin?
Thanks

Update (related to your comments)
This version will work globally on all product variations in the cart for this defined variable product:
add_action('woocommerce_cart_calculate_fees', 'add_custom_discount_2nd_at_50', 10, 1 ); function add_custom_discount_2nd_at_50( $wc_cart ){ if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return; $discount = 0; $items_prices = array(); // Set HERE your targeted variable product ID $targeted_product_id = 40; foreach ( $wc_cart->get_cart() as $key => $cart_item ) { if( $cart_item['product_id'] == $targeted_product_id ){ $qty = intval( $cart_item['quantity'] ); for( $i = 0; $i < $qty; $i++ ) $items_prices[] = floatval( $cart_item['data']->get_price()); } } $count_items_prices = count($items_prices); if( $count_items_prices > 1 ) foreach( $items_prices as $key => $price ) if( $key % 2 == 1 ) $discount -= number_format($price / 2, 2 ); if( $discount != 0 ){ // Displaying a custom notice (optional) wc_clear_notices(); wc_add_notice( __("You get 50% of discount on the 2nd item"), 'notice'); // The discount $wc_cart->add_fee( 'Discount 2nd at 50%', $discount, true ); # Note: Last argument in add_fee() method is related to applying the tax or not to the discount (true or false) } }
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
This code is tested on Woocommerce 3+ and works.
Original answer:
There is many ways to do add a custom discount of 50% on the 2nd item for a specific variable product ID. Below I am using add_fee()
method with a negative value (so it adds a discount).
Optionally it will display a custom notice:
add_action('woocommerce_cart_calculate_fees', 'add_custom_discount_2nd_at_50', 10, 1 ); function add_custom_discount_2nd_at_50( $wc_cart ){ if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return; $discount = 0; // Set HERE your targeted variable product ID $targeted_product_id = 40; foreach ( $wc_cart->get_cart() as $key => $cart_item ) { if( $cart_item['product_id'] == $targeted_product_id ){ $price = $cart_item['data']->get_price(); $quantity = intval( $cart_item['quantity'] ); for( $i = 1, $j = 0; $i <= $quantity; $i++ ){ if( $i % 2 == 0 && $quantity > 1 ) $j++; } if( $quantity > 1 ) number_format($discount -= $price * $j / 2, 2 ); } } if( $discount != 0 ){ // Displaying a custom notice (optional) wc_clear_notices(); wc_add_notice( __("You get 50% of discount on the 2nd item"), 'notice'); $wc_cart->add_fee( 'Discount 2nd at 50%', $discount, true ); # Note: Last argument in add_fee() method is related to applying the tax or not to the discount (true or false) } }
