Step 1: Create a coupon (https://docs.woothemes.com/document/coupon-management/)

Step 2: Add this code in your theme function.php
add_action( ‘woocommerce_before_cart’, ‘apply_matched_coupons’ );

function apply_matched_coupons() {
global $woocommerce;

$coupon_code = ’10percent’; // your coupon code here

if ( $woocommerce->cart->has_discount( $coupon_code ) ) return;

if ( $woocommerce->cart->cart_contents_total >= 500 ) {
$woocommerce->cart->add_discount( $coupon_code );
$woocommerce->show_messages();
}
